Condenser Mechanical Design The condenser will be designed in accordance with HEI Standards using the allowable stresses from the ASME Section VIR Code. The shellside and tubeside do not fall under the jurisdiction of the ASME Code. The shellside and the tubeside will not be code stamped. 2. The condenser will be fabricated in an ASME Section VIH code shop. All welding will be per ASME Section IX. 3. Tube and Shellside Hydrotest A. Tubeside Hydrotest: The waterboxes will be bolted to the tubesheet and the entire tubeside be hydrotested at 1.3 times the tubeside design pressure in the shop. B. Shellside Hydrotest: The shellside will be subject to standing water test in the shop. 4. "Tools" We have included one set of tube removal/installation tools (less driver) in selling price. 5. "Noise" Because of significant influence of customer's piping system and valving, Holtec, will not submit or guarantee noise levels. The evacuation package will achieve sound levels of 85 dba at 3 feet in a free field environment. Based on our prior experience, the condenser does not generate any significant noise. Noise levels in the vicinity of the condenser are generated by the attached rotating equipment and/or caused by customer's drain, return and dump steampipmg and valving. High pressure, high temperature drain returns and dump steam returns do generate noise upon discharge into the condenser, the specific levels being virtually impossible to predict. They are normally of short duration or must be treated locally applied sound attenuating treatment. Holtec will participate in acoustic performance tests in the degree and extent desired by the client 2 6161 Fossil Power Division ®��• Holtec Center, 555 lincoln Drive West, Marlton, NJ 08053 H Q L T E C Telephone (856) 797-0900 1 N T E R N A T 10 N A L Fax (856) 797-1931 on a per diem basis. 6. Painting: A. The external carbon steel surfaces are blasted per SSPC SP 6 and painted with one coat of zinc rich primer. Finish painting by others in the field. B. 'The waterbox internal surfaces are blasted per SSPC SP 10 and painted with 10 -16 mils of Coal Tar Epoxy. C. After fabrication, the shell (wherever accessible) internals will be painted with water- soluble rust preventative. 7. Expansion Joint: An expansion joint is not required for this application. 8. Rupture Disc: We have included one (1) 36" diameter rupture disc for the condenser. Guards & piping for the rupture disc assembly to be provided by others in the field. 9. Tube rolling: The tubes are rolled (no grooves) to the tubesheets. 10. The steam flowrates for the "Min Air temp" seem to be in error. The total turbine exhaust steam flow rate is specified to be 412,9201bs/hr. The BP and LP dump inlet flowrate of specified to be 190,000 lbs/hr and 16,260 lbs/hr. Does dump steam enter the condenser along with the turbine exhaust flowrate? Is the total steam flowrate for the above case the sum of the turbine exhaust flowrate and the dump inlet flow rate. The flowrates need to be verified. Is the calculated duty correct? In the performance table in page xx we have included a separate column for performance in dump mode. 11. The temperature of the LP dump steam was below the saturation temperature. The saturation temperature of steam at 115 psia is 338.0'F. The specification states that the temperature of the LP dump steam is 325.0'F. It is a common industry practice to introduce dry and saturated steam into the condenser. We have increased the temperature of the LP dump steam to 350.0'F (so as to have 157 2 7/66 ®� Fossil Power Division ---- Holtec Center, 555 Lincoln Drive West, Marlton, NJ 08053 H 0 L T E C Telephone (856) 797-0900 1 N T E R N A T 10 N A L Fax (856) 797-1931 some margin above the saturation temperature). This change is reflected in the performance table. 12. We will not submit any detailed design calculations or fabrication drawing. We will provide satisfactory clarification on any issue of the design. 13. We have provided stainless steel 317 tubes and tubesheets. In accordance with the ASME paper included in page 45 of this proposal, 317 stainless steel tubes can withstand chloride content up to 5000 ppm. 16 ■Fossil Power Division _ • Holtec Center, 555 Lincoln Drive West, Marlton, M 08053 H 0 L T E C Telephone (856) 797-0900 1 N T E R N A T 10 N A L Fax (856) 797-1931 - - 1-6 SPARE PARTS LIST A.

The condenser is equipped with a total of 4358 tubes, 0.875" OD, 22 BWG (ave) wall, 31'l0" long made of 317 SS (SA249-317). The tubes are rolled into the 317 SS (SA249-317) tubesheets. The tubesheet is welded to the shell and bolted to the waterbox in a manner such that permits the removal of waterboxes without disturbing the tubesheet or shell. The potential for flow -induced tube vibration is eliminated by using properly drilled tube support plates. The support plate spacing is in accordance with HEI Standards. The support plate spacing is in accordance with HEI standards. The tube-tubesheet joint loads and accompanying tube stress are of prime importance in condenser design. These will be computed using the beam on elastic foundation technique suggested by Heat Exchange Institute Standards for Steam Surface Condensers. Since the performance of the condenser is highly dependent on the efficiency of its devaporizer section and the performance of the vacuum jet air ejector, we have paid particular attention to constructing a highly effective air cooler section. The HOLTEC air cooler design provides for efficient venting of both upper and lower tube passes. The tubes carrying the coldest water are placed in the air cooling zone to achieve maximum depression of the air vapor mixture temperature. The internally built design features prevent the dripping condensate from coming in contact with the air vapor oxygen content in the condenser. The tube bundle is designed to effect free access of steam to the entire tube surface with a minimum amount of pressure loss. At the same time, adequate steam velocities are maintained throughout the bundle to prevent air blanketing of tubes. Finally, the bundle design promotes circulation of steam under the tubes to reheat the condensate as it drips into the hotwell, thereby further reducing the condensate oxygen content. The condenser is provided with a rectangular integral hotwell. The storage capacity of hotwell compartment under normal operating conditions is 1000 gallons. Each compartment of the waterbox is equipped with a 24" diameter manway so as to enable expeditious inspection of tubes and tubesheet. The condenser is designed in accordance with HEI Standards for Steam Surface Condensers.

Field welding is restricted to piping connections. 4.0 DUMP INLET CONNECTIONS: 1. The performance in dump mode is included in page 34 of this proposal. The flowrates in dump mode seem to be in error. Normally there is no turbine exhaust flow in dump mode. The flow rates in the last two columns of the performance table in page 34 need to be verified. 2. Temperature of bypass steam in condenser after expansion: The HP bypass steam expands from 265.0 psis to the condenser equilibrium condenser pressure of 1.47" HgA through a constant enthalpy expansion process. At 1.47" HgA and 1207.9 BTU/1b the steam temperature is 326.5°F. Thus the condenser/turbine internals including the expansion joint will be subject to a maximum temperature of 326.5°F. W ave ' lu a staM�wi allows exp ' t in o pe o ly. The expansion joint is designthstand a continuous opera g temperature of 350.0°F. The shell design temperature is established at 450'F.

There is one (1) bypass inlet headers. The dump inlet pipe is equipped with 500 orifices 1/4" in diameter. The 10" pipe is installed inside a 60" pipe made of carbon steel (with 0.25" corrosion allowance). The steam expands and impinges against the inner walls of the outer cylinder. Two rows of carbon steel rods are placed on top of the tubes for impingement protection. A schematic of the dump inlet is included in page xx of this letter. It should be noted that the dump steam is not expanding inside the condenser shell. The dump steam is not impinging on the shell internals. The dump steam impinges against the inner surface of a 60" diameter pipe which is located external to the shell. In the event of erosion, the entire outer cylinder can be replaced at a very nominal charge. 4. LP Bypass Steam The HP bypass stream (16,260 lbs/hr at 115 psia & 350.0 °F,1190.8 Btu/1b) is introduced into the steam dome through one 6" diameter pipe 18" long made of stainless steel (SA240- 304).

FRANSON Technical Marketing Manager Allegheny Ludkxn Steel Corporation Tubular Products Division Brackenridge, PA ABSTRACT Use of stainless steel, particularly tubing, in steam surface condensers has increased dramat- ically since first use more than forty years ago. Offering good mechanical and physical properties, stainless steels also provide excellent resistance to corrosion in condensers. Attention to cleanli- ness reduces the possibility of pitting and crevice corrosion, the major waterside concerns for stain- less steel surfaces. Ferritic and austenitic alloys with high chromium and molybdenum content resist chloride -containing waters, including sea - waters. Galvanic corrosion, a possibility when coupling stainless steel to other metals in chloride -containing waters, can be mitigated by cathodic protection. However, overprotection can lead to failure of ferritic condenser tube alloys: The utility engineer must consider these factors when deciding on an alloy for condenser use.' Proper selections and subsequent maintenance of stainless steel surfaces will provide the utility with maximum service life. INTRODUCTION Stainless steel has been utilized in steam surface condensers for more than forty years. Tubing was used in air -removal and peripheral sections, replacing non-ferrous metals. Good per- ' raance in these applications led to more exten- sive use. In 1958 the Monongahela Power Company completfly Teteubed a condenser with stainless steel. y"used T304 to replace 88-10-2 brass at their Rivesville Station. Following that first installation the use of stainless steel in con- densers has increased rapidly. Today, it is esti- mated that about 300 million meters (one billion feet) of stainless steel tubing are condensing steam in fossil and nuclear power plants in the United States. Many of these plants utilize stain- less steel for ttbesheets, waterboxes and other condenser components also. Most condenser retubings since Rivesville have also involved T304 stainless whose performance in fresh water has been excellent. Type 316 stainless steel, used in more aggressive polluted or natural waters, has fared well when cleanliness and freedom from deposits has been maintained. However, T316 has suffered pitting and crevice corrosion in many seawater applications and has generally been replaced with other materials. Today, a number of stainless steels are available which are capable of handling seawater as well an other condenser con- ditions. This paper reviews the many stainless steels which are available, some of then new, which have properties of use to condenser design. Attention is paid to references concerning performance of stainless steel in steam and water envirotmtents. Where possible, original illustrative data are used but other data from the literature are cited. It is hoped the information will assist the utility engineer to make proper selection of a material for his condenser application. ALLOYS AVAILABLE The American Iron and Steel Institute lists about 60 grades of stainless steel. At least an equal number of proprietary alloys are available, some of them designed specifically for condenser service. These alloys fall into three main groups: austenitic, ferritic, and duplex or two-phase. Each alloy group has characteristic properties. Austenitic Alloys- . A sample of austenitic stainless steels is given in Table 1 and typical microstructure is shown in Figure 1. Nickel varies from -about 9 percent up to more than 30 percent. Chromium is present from about 17 to about 28 percent and molybdenum up to 6.5 percent. About-0.2 percent of nitrogen is present in some of the newer steels Presented at the h.

The nitrogen increases strength, contributes to pitting and crevice corro- sion resistance, and also suppresses formation of deleterious intermetallic phases which tend to form in the highly alloyed austenitic alloys(2).

The AL-6X" alloy has been used for more than ten years in thin -walled condenser tubing for sea- water service. Testing of this alloy began in 1970 and the first full condenser retubing occurred in 1974. Today, there are more than 7 million meters (23 million feet) of AL-6X alloy condenser tube in service. - ALA- XN and AL-6X are Trademarks of Allegheny Ludlum Steel Corporation. Ferritic fisting Alloys A of representative ferritic stainless steels is given in Table 2 and a typical microstruc- ture is shown in Figure 2. Although T430 ferritic condenser tube ppeerformed well in tests during the 40's and 50's(31, T304 became the standard fresh- water alloy. The other ferritic alloys in Table 2 are relatively new, having evolved as a result of A00 and vacuum steel -making capabilities. Carbon and nitrogen contents of these new ferritic alloys are kept low which helps to overcome some of the problems with ductility inherent in the standard 400 Series ferritic stainless steels. 2 TABLE 2 Representative Ferritic and Duplex Stainless Steels Typical Con_ Wt.% All o N� Cr o Ot eFi r Fer�ri�tic _ 16 - - XM-8 (T439) - 18 - .6171 18-2 (T444) 18 2 .3Ti, .30 XM-27 (E-MITE') - 26 1 .1Cb ) 25-4-4 (MONIT") 4 25 4 . 26-3-3 (Sea Cure-) 2 26.5 29 4.5 .3Ti5Ti25Cb AL 29-4C' 29 4 29-4 (AL 29-4") - - 29-4-2 (AL 29-4-2") 2 29 4 D piex 5 26 T329 2.7 3 - A669 5 18.5 ASN 2205 5 22 3 ,17N, 1.7Cu Ferralium 255" 5.5 26 3 L 29Trademarks and A n Allegheny LSteel are Corporation - MONIT, Trademark of Nyby-Uddeholm - Sea Cure, Trademark of Crucible, Inc. - Ferralium 255, Trademark of Langley Alloys CA figure 2.

Picric -Hydrochloric Acid Etch. 35 Besides low carbon and nitrogen content, the new ferritic alloys generally contain titanium and/or columbium for stabilization against inter - granular corrosion. Chromium in these alloys varies from 18 to 29 percent. Up to 4 percent molybdenum and nickel may also be present. The XM-8 (T439) tubing was introduced to fresh water condensers in 1949. Several utility and sur- face condensers were retubed with this alloy in the date 70's. In addition, the XM-8 alloy is also being used in feedw t heaters(4) and moisture separator reheaters�5 . Vacuum -melted 29-4 ferritic alloy tubes were placed on test in a sea- water cooled condenser in 1975. The excellent per- formance of these tubes led to the development of the lower -cost, A00-refined AL 29-4C" ferritic con- denser tube alloy. The first full retubing with a superferritic, the AL 294C alloy, occurred in 1980. Since that time, more than 8 million meters 124 million feet) of high alloy ferritic condenser tube have been installed in condensers in U.S. util- ities. Duplex Alloys The microstructure of the duplex alloys con- sists of half austenite and half ferrite as shown in Figure 3. Compositions given in Table 2, typi- cally contain about 5 percent nickel. Chromium ranges from about 18 to about 26 percent and molybdenum may be as high as 3 percent. The newer alloys .also contain nitrogen which aids in leveling out composition differences between the austenite and ferrite phases. steel, typical of two-phase, duplex alloys. 500X Magnification, 10% Oxalic Acid Etch, Electrolytic. - AL�C- is a Trademark of Allegheny Ludlum Steel Corporation 47M In the 50's the duplex T329, along with T304 and other alloy condenser tubes, was placed on test in river water polluted with acid mine waters. No corrosion was observed on any of the alloys and T3D4 stainless emerged as the material of choice for these waters. Although not widely used by utilities yet, the duplex stainless steels, particu- larly the 2205 alloy, are finding expanded interest in the U.S. because of their high strength combined with good resistance to corrosion. MECHANICAL PROPERTIES Mechanical properties for selected alloys are given in Table 3. Strength increases with increasing alloy content. Nitrogen is a particu- larly potent strengthener as can be seen by com- paring the properties of the AL-6XN alloy with those of the AL-6X alloy. As a group, the aus- tenitic alloys are characterized by large tensile elongation values. The ferritic and duplex alloys have less ductility. Ferritic steel tubing has sufficient ductility to be roller expanded and flared into tubesheets. However, since they have less inherent ductility and tend to be notch sensitive, they require greater care. heedless to say, steps should be taken with all condenser tubing, austenitic or ferritic, to avoid work hardening the tube ends which could lead to loss of ductility.

Source: J. R. Maurer, Ref. 7. The thermal conductivity of the ferritic XM-8 (T439) alloy is about 50 percent greater than that of the austenitic T304 alloy of same chromium con- tent. This translates into somewhat better heat transfer capabilities for the XM-8 (T439) alloy. As a group, the stainless steels have lower thermal conductivities than copper -base alloys. However, it has been shown that thermal conductivity jjs only a small contributor to overall heat transferi8).. Steam- and water -side film and fouling coefficients are much stronger influences. Because stainless steel surfaces do not generally corrode in the con- denser environment and remain relatively clean during service ,(lhemr�vide excellent heat trans- fer performance The thermal expansion coefficients for ferritic stainless steels are close to those for carbon steel. This may be an important design con- sideration. Expansion coefficients for the aus- tenitic alloys are about 60 percent greater. The - duplex alloys exhibit intermediate values, consis- tent with their austenite-ferrite microstructure. CORROSION RESISTANCE Not all stainless steels are capable of handling all environmental conditions, particularly water side conditions, which can be encountered in utility surface condensers. Thus, it is important for the utility engineer to understand the effects of stainless steel structure and alloy content on resistance to the various forms of corrosion - encountered is the condenser environment.

However, natural waters often contain chlorides; 10 to-100 ppm for surface waters and up to 19,000 ppm for seawater. Pitting and crevice corrosion from chlorides are the leading causes of failure of stainless steel in the condenser environment. Although a possibility, there are no reported failures of stainless steel by stye$$ orrosion cracking in condenser service`�2�• Hard waters, which form calcium c 4nate scale, are protective of carbon steel, 5llcrevice but could be responsible for under -deposit corrosion of stainless steel when chlorides are present. Manganese oxide deposits from waters have 3�' CU 4q�66 also caused failure of stainless steel tubing because they promote crevice corrosion(12). Polluted seawater often contains hydrogen sulfide whish2Is highly corrosive toward copper - base alloysltll There is evidence that sulfides may accelerate pitting or cruise corrosion of susceptible stainless steels Hower, more highly alloyed stainless steels, normally resistant to chloride -bearing � t6grs, are not affected by the presence of sulfides )). Much stainless steel condenser tubing is. in service today in polluted saline waters having replaced sulfide corroded copper -base alloys. Stress -Corrosion Cracking (SCC) tress -corrosion cracking (SCC) is a major cause for corrosion failure of austenitic stainless steels in environments other than condensers. No SCC failures are on record in steam surface conden- sers, probably because temperatures of cooling waters are too )ow. Conditions which might cause temperatures to exceed 600C (140°F) could, con- ceivably, lead to SCC failures. In addition to temperature, tensile stresses and chlorides are requirements for SCC. Low levels of chloride, i.e. 10 ppm or even less, are sufficient for SCC of susceptible alloys if a chloride -concentrating mechanism such as crevices or wet -dry action, are present. Austenitic stainless steels with about 9 per- cent nickel are t1l��g st susceptible to SCC as shorn in Figure 4 "77and Table 6. Alloys with high nickel content e.g. 904L. the AL-6X and AL-6XN alloys and similar materials, are substantially more resistant to SCC than T304 or T316 stainless, and do not crack in sodium chloride environments, even when very hot. 1000 e• 0 E: W sf 3ti 100 Cracking c V �F ti No Cracking 10 �& c 10 20 40 60 8o 10C Hickiei-Per C*M Figure 4.

The performance of the 2205 alloy, for instance, is similar to that of the nickel -containing 29-4-2 ferritic alloy and the high -nickel austenitic alloys (Table Q; The duplex alloys generally hold up well to-SCC by sodium chloride environments. Pitting and Crevice Corrosion Stainless steels maybe subject to pitting and crevice corrosion in the presence of chloride ion depending on alloy composition and water conditions. Clean surfaS)and flowing water provide the best performance Under stagnant water conditions the protective oxide surface film on stainless steel can be penetrated by chloride ions. Crevices permit localized stagnation even with flowing water. Once the oxide film is penetrated metal chlorides - concentrate in the crevice and hydrolysis produces very acidic conditions. Crevice corrosion can prop- agate rapidly and may cause perforation of thin 50l6a; ' wall condenser tubes. Crevice corrosion is the predominant form of corrosion obs�1v7d on stainless steel in steam surface condensers . Crevices may exist because of design or due to water conditions in the condenser. Tube-to- tubesheet joints and gasket surfaces are examples of crevices incorporated into the condenser by design. Calcium carbonate scale, manganese dioxide deposits and marine growth of various kinds, are examples of crevices which form due to water con- ditions Whatever the source, crevices are potential sites for corrosion when chlorides are present. Conditions are aggravated by high chloride content, high temperature, high oxygen level and low pH of water. Crevice geometry is an important f�tor in determining whether corrosion will occur. Chromium and molybdenum, particularly when used together, promote resistance to pitting and crevice corrosion of stainless steel.

Other data illustrate that increasing temperature of a h 441 ide-bearing water necessitates more Cr and Mo`2 A 10 percent solution of ferric chloride is used to evaluate resistance to pitting and crevice corrosion. This oxidizing, low pH (about 1), environment approximates conditions within a crevice during corrosion of stainless steel. Temperature increased in steps until corrosion is observed(). Such "critical crevice corrosion temperature" (CCT) data for a variety of stainless steels are given in Table 9. The highest CCT values, 50"C (122°F), representing the best resis- tance to chloride crevice corrosion, belong to the ferritic AL 294C and 29-4 alloys which contain 29 percent chromium and 4 percent molybdenum:.The austenitic stainless steels with highest CCT values, 40"C, are those with 20 percent chromium, 6.5 percent molybdenum and also nitrogen (0.2%) such as the AL-6XN alloy.

The AL-6X alloy has been in use for more than ten years as -thin walled con- denser tube for seawater service. The new AL-6XN alloy, containing 0.2 percent nitrogen can be pro- duced in plate sections and, in add jt on, offers better crevice corrosion resistancel(Z (Table 9). Plate sections up to 38 mm (1.5 in.) have been used for tubesheets for heat exchangers using seawater in chemical plants. The alloy is.weidable and is well suited, therefore, for tubesheets, waterboxes, piping and other condenser components, as well as tubing, for contact with seawater or other high - chloride cooling waters. Several ferritic alloys for use with seawater are included in Table 10. These contain from 25 to 29 percent chromium and 3 to 4 percent molybdenum. The 29Cr-4Mo alloys, with highest chromium and molybdenum content, are the most resistant of all the stainless steels to chloride crevice corrosion. Some Precautions when Using Stainless Steels in Seawater Stainless steels are more noble than copper - base alloys in the seawater galvanic series. Galvanic corrosion of copper -base alloy tubesheets may, therefore, be experienced following retubing with a high alloy stainless steel. Cathodic pro- tection systems and cot pgs.have been used to et alleviate this problem i change i material to a seawater -resistant stainless steel such as the AL-6XN alloy or similar composition would also solve this problem. Ferritic stainless steels may be e�bilttled by cathodic protection systems in seawater r. Over- protection of steel waterboxes with potentials more electronegative than -0.80 volts (SCE) causes large volumes of hydrogen gas to be generated which has been the cause of brittle fail��rr f a few high - alloy ferritic condenser tubesi46-12) Restricting the cathodic protection system potentials to values no more electronegative than -0.80 volts (SCE) has eliminated the embrittlement problem while still provi g 31Qtection to tubesheets and water- boxes�pi)t3), Recently, the high -chloride; highly acidic corrosion product resulting from crevice corrosion on a T316 tubesheet hole has been observed to attack adjacent AL 294C y tubes, causing per- foration in extreme cases, Tests to investi- gate this corrosion verify that T316 stainless steel and other grades which are subject to crevice corrosion in seawater, can initiate corrosion on high alloy ferritic stainless steels which are otherwise resistant to seawater. Results suggest that alloys which do not suffer crevice corrosion in seawater, such as the AL-6XN alloy, do not initiate attack of the high alloy ferritic steels. The AL-6XN alloy, and similar steels, therefore, are good candidates -for tubesheets to be used with high alloy ferritic tubes. Also, the results suggest that the seawater -resistant austenitic alloys, AL-6X and AL-6XN, are not subject to corro- sion in contact with T316 even though crevice corrosion is occurring. As mentioned previously, there have been some ,failures of 1304 stainless condenser tubes due to corrosion under manganese deposits. Likewise, T316 tubes have failed in seawater because of crevice corrosion. Failure tq drain a condenser during lay-up, allowing stagnant, chloride -bearing water to reamin in contact with the tubes has also been i reason for failure. High alloy austenitic and ferritic tubing has been used for retubing in a number of such situations. AL-6X alloy tubing was installed in a seawater condenser more than nine years ago. Some pitting corrosion has been observed but less than 0.15 percent failures have been observed. The -nitrogen -modified AL -UN alloy and the high Cr and No ferritic steels demonstrate better pitting resistance (Table 9) and can be.ex- pected to provide even better resistance than the original AL-6X alloy. SUMMRY Stainless steel has been used to resist corrosion in steam surface condensers for more than forty years. Performance in general has been very good. As a group, the stainless steels resist steam side corrosion and wet steam impingement attack. Some failures of stainless steel have occurred from the -water side, due to chloride crevice corrosion. Chromium and, especially, molybdenum are required for resistance to crevice corrosion. Nitrogen has also been found to enhance crevice corrosion resistance of austenitic stain- less steels. Alloys which are most resistant to chloride crevice corrosion contain the highest level of these elements. Today, there are a variety of austenitic, ferritic ad duplex stain- e different less steels which are appropriate water conditions available to utilities. Different alloys are appropriate for fresh water•, brackish water or seawater cooling. Some of these alloys were developed specifically with the condenser envi- ronment in mind. With proper selection and main- tenance, stainless steels will provide many years of trouble -free -service. REFERENCES 1.

Selection of Stainless Steel For Steam Surface Condenser Applications IVAN A. FRANSON Technical Marketing Manager Allegheny Ludlum Steel Corporation Tubular Products Division Brackenridge, PA ABSTRACT Use of stainless steel, particularly tubing, in steam surface condensers has increased dramat- ically since first use more than forty years ago. Offering good mechanical and physical properties, stainless steels also provide excellent resistance to corrosion in condensers. Attention to cleanli- ness reduces the possibility of pitting and crevice corrosion, the major waterside concerns for stain- less steel surfaces. Ferritic and austeoitic alloys with high chromium and molybdenum content resist chloride -containing waters, including sea - waters. Galvanic corrosion, a possibility when coupling stainless steel to other metals in chloride -containing waters, can be mitigated by cathodic protection. However, overprotection can lead to failure of ferritic condenser tube alloys: The utility engineer must consider these factors when deciding on an alloy for condenser use.' Proper selection and subsequent maintenance of stainless steel surfaces will provide the utility with maximum service life. INTRODUCTION Stainless steel has been utilized in steam surface condensers for more than forty years. Tubing was used in air -removal and peripheral sections, replacing non-ferrous metals. Good per- :ormance in these applications led to more exten- sive use. In 1958 the Monongahela Power Company completily retubed a condenser with stainless steel.( They -used T304 to replace 88-10-2 brass at their Rivesville Station. Following that first installation the use of stainless steel in con- densers has increased rapidly. Today, it is esti- mated that about 300 million meters (one billion feet) of stainless steel tubing are condensing steam in fossil and nuclear power plants in the United States. Many of these plants utilize stain- less steel for tubesheets, waterboxes and other condenser components also. Most condenser retubings since Rivesville have also involved T304 stainless whose performance in fresh water has been excellent. Type 316 stainless steel, used in more aggressive polluted or natural waters, has fared well when cleanliness and freedom from deposits has been maintained. However, T316 has suffered pitting and crevice corrosion in many seawater applications and has generally been replaced with other materials. Today, a number of stainless steels are available which are capable of handling seawater as well as other condenser con- ditions. This paper reviews the many stainless steels which are available, some of then new, which have properties of use to condenser design. Attention is paid to references concerning performance of stainless steel in steam and water environments. Where possible, original illustrative data are used but other data from the literature are cited. It is hoped the information will assist the -utility engineer to make proper selection of a material for his condenser application. ALLOYS AVAILABLE The American Iron and Steel Institute lists about 60 grades of stainless steel. At least an equal number of proprietary alloys are available, some of them designed specifically for condenser service. These alloys fall into three main groups: austenitic, ferritic, and duplex or two-phase. Each alloy group has characteristic properties. Austenitic Alms Awe of austenitic stainless steels is given in Table 1 and typical microstructure is shown in Figure 1. Nickel varies from -about 9 percent up to more than 30 percent. Chromima is present from about 17 to about 28 percent and molybdenum up to 6.5 percent. About.0.2 percent of nitrogen is present in some of the newer steels Presented at the Jt ASMEAEEE Power Generation Conference Milwaukee. WieowWn — Oct W 20-24.1985 3y 46%6' such as the AL-6XN" alloy. The nitrogen increases strength, contributes to pitting and crevice corro- sion resistance, and also suppresses formation of deleterious intermetallic phases which trd to form in the highly alloyed austenitic alloys(( TABLE I Representative Austenitic Stainless Steels Typical Composition, Wt.% AlloyNi Cr Mo other T304L 10 19 - - T316L 12 17 2.5 - T317L 13 19 - 3.5 - T317LMo 14.5 18.5 4.3 0.15N 904L 24.5 21 4.5 1.5Cu AL-6X" 24.5 20 6.5 - AL-6XN" 24.5 20 6.5 0.2N Sanicro 28" 31 27 3.5 ICU Carpenter 2003" 34 20 2.5 3.50, 0.50 Carpenter 20Mo6" 35 24 6.0 3Cu " - AL-6X and AL-6XN, Trademarks Allegheny Ludlum Steel Corporation Sanicro 28, Trademark Sandvik•, Inc.

The AL-6X" alloy has been used for more than ten years in thin -walled condenser tubing for sea- water service. Testing of this alloy began in 1970 and the first full condenser retubing occurred in 1974. Today, there are more than 7 million meters (23 million feet) of AL-6X alloy condenser tube in service. AL-6XN and AL-6X are Trademarks of Allegheny Ludlum Steel Corporation. 2 Ferritisting oc Alloys fif representative ferritic stainless steels is given in Table 2 and a typical microstruc- ture is shown in Figure 2. Although T430 ferritic condenser tube performed well in tests during the 40's and 50's(3. T304 became the standard fresh- water alloy. The other ferritic alloys in Table 2 , are relatively new, having evolved as a result of A00 and vacuum steel -making capabilities. Carbon and nitrogen contents of these new ferritic alloys are kept low which helps to overcome some of the problems with ductility inherent in the standard 400 Series ferritic stainless steels.

Microstructure of XM-8 (T439) stainless steel, typical of tion.ferri Picric ilydrochloricc Acid Etch. 3S Besides low carbon and nitrogen content, the new ferritic alloys generally contain titanium and/or columbium for stabilization against inter - granular corrosion. Chromium in these alloys varies from 18 to 29 percent. Up to 4 percent molybdenum and nickel may also be present. The XM-8 (17439) tubing was introduced to fresh water condensers in 1949. Several utility and sur- face condensers were retubed with this alloy in the late 701s. In addition, the XM-8$ alloy is also being used in feedNjr heaters- ) and moisture separator reheatersll )). Vacuum -melted 29-4 ferritic alloy tubes were placed on test in a sea- water cooled condenser in 1975. The excellent per- formance of these tubes led to the development of the lower -cost, AOD-refined AL 29-4C" ferritic con- denser tube alloy. The first full retubing with a superferritic, the AL 29-4C alloy, occurred in 1980. Since that time, more than 8 million meters 124 million feet) of high alloy ferritic condenser tube have been installed in condensers in U.S. util- ities. Duplex Alloys The microstructure of the duplex alloys con- sists of half austenite and half ferrite as shown in Figure 3. Compositions given in Table 2, typi- cally contain about 5 percent nickel. Chromium ranges from about 18 to about 26 percent and molybdenum may be as high as 3 percent. The newer alloys also contain nitrogen which aids in leveling out composition differences between the austenite and ferrite phases. figure 3.

No corrosion was observed on any of the alloys and T304 stainless emerged as the material of choice for these waters. Although not widely used by utilities yet, the duplex stainless steels, particu- larly the 2205 alloy, are finding expanded interest in the U.S. because of their high strength combined with good resistance to corrosion. MECHANICAL PROPERTIES Mechanical properties for selected alloys are given in Table 3. Strength increases with increasing alloy content. Nitrogen is a particu- larly potent strengthener as can be seen by com- paring the properties of the AL-6XN alloy with those of the AL-6X alloy. As a group, the aus- tenitic alloys are characterized by large tensile elongation values. The ferritic and duplex alloys have less ductility. Ferritic steel tubing has sufficient ductility to be roller expanded and flared into tubesheets. However, since they have less inherent ductility and tend to be notch - sensitive, they require greater care. Needless to say, steps should be taken with all condenser tubing, austenitic or ferritic, to avoid work - hardening the tube ends which could lead to loss of ductility.

All stainless steels have elastic modulus values in the range 186 to 207 GPa (27 to 30 million psi) which aid in minimizing vibration pro¢�gms. Based on formulas developed by Peake et. altl ,•Maurer showed that thin -walled stainless steel tubing can replace Admiralty bra s)without modification of support plate spacing Titanium tubing with low elastic modulus, requires relatively heavy wall thickness or installation of extra support plates or stakes, to avoid vibration damage (Table 5).

Source: J. R. Maurer, Ref. 7. U The thermal conductivity of the ferritic XM-8 (17439) alloy is about 50 percent greater than that . of the austenitic T304 alloy of same chromium con- tent. This translates into somewhat better heat transfer capabilities for the XM-8 (T439) alloy. As a group, the stainless steels have lower thermal conductivities than copper -base alloys. However, it has been shown that thermal conductivity jo my a small contributor to overall heat transfer! Steam- and water -side film and fouling coefficients are much stronger influences. Because stainless steel surfaces do not generally corrode in the con- denser environment and remain relatively clean during service, tt gg ppr vide excellent heat trans- fer performance(Ift 5�• The thermal expansion coefficients for ferritic stainless steels are close to those for carbon steel. This may be an important design con- sideration. Expansion coefficients.for the aus- tenitic alloys are about 60 percent greater. The. duplex alloys exhibit intermediate values, consis- tent with their austenite-ferrite microstructure. CORROSION RESISTANCE Not all stainless steels are capable of handling all environmental conditions, particularly water side conditions, which can be encountered in utility surface condensers. Thus, it is important for the utility engineer to understand the effects of stainless steel structure and alloy content on resistance to the various forms of corrosion - encountered in the condenser environment. Steam Side Corrosion e stainless —steels, as a group, are highly resistant to the steam side environment of a sur- face condenser. They are generally considered to be immune to corrosion by steam condensate contaior carbon dioxidnj38)?11yen•Stainlessasteel tubing has dioxides replaced corroding copper -base alloys jlOdir- removal sections' of surface condensers(! ) Stainless steel is also highly resistant, though not totally immune, to wet steam impingement attack or erosion -corrosion which, again, has been the cause fa�1 4.

However, naturalwaters often contain chlorides; 10 lseawater. Pitting waters and up to 19,000 ppm for and crevice corrosion from chlorides are the leading causes of failure of stainless steel in the condenser environment. Although a possibility, there are no reported failures of stainless steel by stye$$ rrosion cracking in condenser service` T Hard waters, which form calcium c 19gnate scale, are protective of carbon steel, but could be responsible for under -deposit or crevice corrosion of stainless steel when chlorides are present. Manganese oxide deposits from waters have 3} also caused failure of stainless steel tubing because they promote crevice corrosion(12). Polluted seawater often contains hydrogen sulfide whith21s highly corrosive toward copper - base alloys There is evidence that sulfides may accelerate pitting or cr��* a corrosion of susceptible stainless steels !. However, more highly alloyed stainless steels, normally resistant to chloride -bearing w rs, are not affected by the presence of sulfides(16 . Much stainless steel condenser tubing is. in service today in polluted saline waters having replaced sulfide corroded copper -base alloys. Stress -Corrosion Cracking (SCC) tress-corros on cracking (SCC) is a major cause for corrosion failure of austenitic stainless steels in environments other than condensers. No SCC failures are on record in steam surface conden- sers, probably because temperatures of cooling waters are too low. Conditions which might cause temperatures to exceed 60°C (1400F) could, con- ceivably, lead to SCC failures. In addition to temperature, tensile stresses and chlorides are requirements for SCC. Low levels of chloride, i.e. 10 ppm or even less, are sufficient for SCC of susceptible alloys if a chloride -concentrating mechanism such as crevices or wet -dry action, are present. Austenitic stainless steels with about 9 per- cent nickel are ta�ggmost susceptible to SCC as shown in Figure 4�i7) and Table 6. Alloys with high nickel content e.g. 904L, the AL-6X and AL-6XN alloys and similar materials, are substantially more resistant to SCC than T304 or T316 stainless, and do not crack in sodium chloride environments, even when very hot. 1000 LO 100 Cracking r 4 fa No Cracking 10 a c L 1 J 20 40 60 an ten 0 N1Ck* Per Gent Figure 4.

The nickel -free ferritic alloys, such as XM-8 (T439), XM-27, AL 29-4C and 29-4 are essentially immune to SCC and resist the harsh boiling magne- sium chloride solution (Table 6). The presence of nickel in a ferritic alloy causes a decrease in SCC resi$i Qce as revealed by the magnesium chloride testa . The nickel -containing ferritic alloys maintain high resistance to sodium chloride environ- ments. Duplex stainless steels offer improved SCC resistance because half their microstructure con- sists of ferrite. The performance of the 2205 alloy, for instance, is similar to that of the nickel -containing 29-4-2 ferritic alloy and the high -nickel austenitic alloys (Table Q& The duplex alloys generally hold up well to-SCC by sodium chloride environments. Pitting and Crevice Corrosion Stainless steels may subject to pitting and crevice corrosion in the presence of chloride ion depending on alloy composition and water conditions. Clean surfaimand flowing water provide the best performance . Under stagnant water conditions the protective oxide surface film on stainless steel can be penetrated by chloride ions. Crevices permit localized stagnation even with flowing water. Once the oxide film is penetrated metal chlorides - concentrate in the crevice and hydrolysis produces very acidic conditions. Crevice corrosion can prop- agate rapidly and may cause perforation of thin wall condenser tubes. Crevice corrosion is the predominant form of corrosion obsgrvid on(20) on stainless steel in steam surface condensers)) . Crevices may exist because of design or due to water conditions in the condenser. Tube-to- tubesheet joints and gasket surfaces are examples of crevices incorporated into the condenser by design. Calcium carbonate scale, manganese dioxide deposits and marine growth of various kinds, are examples of crevices which form due to water con- ditions Whatever the source, crevices are potential sites for corrosion when chlorides are present. Conditions are aggravated by high chloride content, high temperature, high oxygen level and low pH of water. Crevice geometry is an important fg�tor in determining whether corrosion will occur. Chromium and molybdenum, particularly when used together, promote resistance to pitting and crevice corrosion of stainless steel. Eletcro- chemical polarization data (Table 7) TABLE 7 Effect of Chromium and Molybdenum Content on Pitting Potential of•Ferritic Stainless Steel in Deaerated Synthetic Sea Water, 90C (194F), pH 7.3 Increase in Pitting Potential With Alloying Element Alloying Addition Cr Alone (20-40% Cr) 4.4 mV/% Cr Mo at 20% Cr (0-10% Mo) 58.5 mV/% Ho Mo at 30% Cr (0-5% Mo) 125 mY/% MD Source: H. Pessal et. al., Ref. 22. illustrate(22) that molybdenum additions to high chromium alloys are far more effective in improving pitting resistance than when chromium is increased alone. Nitrogen also improves resistance of au$s- tenitic steels to pitting and crevice c(g3rg lon{2) in addition to chromium anj6jolybdenum Copper may be detrimental Pitting potential data (Table 8) further illustrate the benefits of high chromium and molybdenum and point out that as chloride content of water is increased, more of these elements are needed. Other data illustrate that increasing temperature of a 91fide-bearing water necessitates more Cr and Mo A 10 percent solution of ferric chloride is used to evaluate resistance to pitting and crevice corrosion. This oxidizing, low pH (about 1), environment approximates conditions within a crevice during corrosion of stainless steel. Temperature increased in steps until corrosion is observed Such "critical crevice corrosion temperature" (CCT) data for a variety of stainless steels are given in Table 9. The highest CCT. values, 50"C (1220F), representing the best resis- tance to chloride crevice corrosion, belong to the ferritic AL 29-4C and 29-4 alloys which contain 29 percent chromium and 4 percent moiybdenum:.The austenitic stainless steels with highest CCT values, 40*C, are those with 20 percent chromium, 6.5 percent molybdenum and also nitrogen (0.2%) such as the AL-6XN alloy.

Careful consideration should be given•iiefore using the alloys (or other stainless steels of similar composition) in -waters containing higher chloride levels than those listed in the left-hand column of Table 10. Alloys listed under higher chloride levels can be considered for all waters containing lower chloride content.

The ratings in Table 10 are a result of information gleaned from the literature combined with internal test results and personal observa- tions. It must be emphasized that for nearly every condition listed, information exists implying the alloy belongs in another category. The intent of Table 10 is to emphasize again that not all stain- less steels are appropriate for all water condi tions and also that some stainless alloys are available which can handle even the most aggressive cooling waters, such as seawater. Selection for Fresh Water Alloys containing 1W percent chromium are con- sidered to be suitable for waters with ppm chlorides under crevice conditions (21tt E�pppp )(�8'(29). Alloys containing about 18 percent chromium and about 2 percent molybdenum are more resistant to pitting and crevice corrosion and are considered to be suitable for w tt RS 44��1Mt8 g up to about 1000 ppm chloride Cal Selection for Brackish Waters For waters conta n ng up to about 5000 ppm chlorides, austenitic alloys containing about 19 percent chromium and 3.5 percent molybdenum are considered(3$)t131e(y1ficient crevice corrosion resistance (t l The.duplex T329 alloy is also expected to provide resistance. Higher concen- tration of chlorides in brackish waters, i.e. up to 10,000 ppm chloride, requires additional alloy con- tent. Alloys expected to perform well at these chloride levels are: the austenitic T317LMo, 904L and 2OMo6" alloys, the ferritic XM-27 alloy, and the duplex 2205 and ferralium 255" alloys and other alloys with similar chromium and molybdenum con- tents. .These are alloys which have been usedor tested in seawater and have been(0)t32)(3�36), good but not complete resistance Selection for Seawater Stainless steel has, been used in seawater - cooled condensers for two primary reasons. The ifirst of tthh se is excellent resistance to sulfides(161. The second reason is excellent resistance to erosion -corrosion which has been a signifMat cause of failure of copper base alloys(( Stainless steels are resistant to erosion -corrosion in seawater even wjl��velocities in excess of 36 m/sec (100 ft./sec.) .• AL-6X stainless alloy tube inserts have been employed with considerable success to alleviate corer base alloy tubing inlet end erosion -corrosion Type 316 stainless steel condenser- tubes were originally used for seawater service but failure rate was high a?I MM. tubes were replaced with other materials( With careful maintenance to keep surfaces clean and free of demits, some T316 tubing has provided good service However, even with careful cleaning, the crevice between tube and tubesheet can be the site of severe corro- sion of T316 in seawater. As indicated in Table 10,_a number of staiq less steels are availabje which are considered tq- be resistant to seawater. The sgaworthy au$tedtiC alloys combine chromium (up tg 24 perce4tl with high molybdenum (up to 6.5 percent Y and spire ZOMo7-is a Trademark of Carpenter Technology Corporation Ferralium 255 is a Trademark of Langley Alloys. contain, in addition, nitrogen for added crevice corrosion resistance. The AL-6X alloy has been in use for more than ten years as -thin walled con- denser tube for seawater service. The new AL-6XN alloy, containing 0.2 percent nitrogen can be pro- duced in plate sections and, in add Mon, offers better crevice corrosion resistance (Table 9.). Plate sections up to 38 mm (1.5 in.) have been used for tubesheets for heat exchangers using seawater in chemical plants. The alloy is. weldable and is well suited, therefore, for tubesheets, waterboxes, piping and other condenser components, as well as tubing, for contact with seawater or other high - chloride cooling waters. Several ferritic alloys for use with seawater are included in Table 10. These contain from 25 to 29 percent chromium and 3 to 4 percent molybdenum. The 29Cr-4Mo alloys, with highest chromium and molybdenum content, are the most resistant of all the stainless steels to chloride crevice corrosion. Some Precautions When Using Stainless Steels in Seawa er Stainless steels are more noble than copper - base alloys in the seawater galvanic series. Galvanic corrosion of copper -base alloy tubesheets may, therefore, be experienced following retubing with a high alloy stainless steel. Cathodic pro- tection systems and coMrs.have been used to alleviate this problem ) A change in tubesheet material to a seawater -resistant stainless steel such as the AL-6XN alloy or similar composition would also solve this problem. Ferritic stainless steels may be amb' ttled by cathodic protection systems in seawater Over- protection of steel waterboxes with potentials more electronegative than -0.80 volts (SCE) causes large volumes of hydrogen gas to be generated which has been the cause of brittle fair �_$ff)a few high - alloy ferritic condenser tubesr44 Restricting the cathodic protection system potentials to values no more electronegative than -0.80 volts (SCE) has eliminated the embrittlement problem while still prov1JJ??(gr tection to tubesheets and water- boxes Recently, the high -chloride; highly acidic corrosion product resulting from crevice corrosion on a T316 tubesheet hole has been observed to attack adjacent AL 294C�y tubes, causing per- foration in extreme cases Tests to investi- gate this corrosion verify that T316 stainless steel and other grades which are subject to crevice corrosion in seawater, can initiate corrosion on high alloy ferritic stainless steels which are otherwise resistant to seawater. Results suggest that alloys which do not suffer crevice corrosion in seawater, such as the AL-6XN alloy, do not initiate attack of the high alloy ferritic steels. The AL-6XN alloy, and similar steels, therefore, are good acandidates-for ferritic tubes. Also, the results with sul highlloy suggest that the seawater -resistant austenitic alloys, AL-6X and AL-6XN, are not subject to corro- sion in contact with T316 even though crevice corrosion is occurring. As mentioned previously, there have been some ;failures of 1304 stainless condenser tubes due to corrosion under manganese deposits. Likewise, T316 tubes have failed in seawater because of crevice corrosioni. Failure tp (!rain a condenser during lay-up, allowing stagnant, chloride -bearing water to reamin in contact with the tubes has also been a reason for failure. Nigh alloy austenitic and ferritic tubing has been used for retubing in a number of such situations. AL-6X alloy tubing was installed in a seawater condenser more than nine years ago. Some pitting corrosion has been observed but less than 0.15 percent failures have been observed. The nitrogen -modified AL-6XN alloy and the high Cr and Mo ferritic steels demonstrate better pitting resistance (Table 9) and can be ex- pected to provide even better resistance than the original AL-6X alloy. SUMMARY Stainless steel has been used to resist corrosion in steam surface condensers for more than forty years. Performance in general has been very good. As a group, the stainless steels resist steam side corrosion and wet steam impingement attack. Some failures of stainless steel have occurred from the water side, due to chloride crevice corrosion. Chromium and, especially, molybdenum are required for resistance to crevice corrosion. Nitrogen has also been found to enhance crevice corrosion resistance of austenitic stain- less steels. Alloys which are most resistant to chloride crevice corrosion contain the highest level of these elements. Today, there are a variety of austenitic, ferritic and duplex stain- less steels which are appropriate for the different water conditions available to utilities. Different alloys are appropriate for fresh water, brackish water or seawater cooling. Some of these alloys were developed specifically with the condenser envi- ronment in mind. With proper selection and main- tenance, stainless steels will provide many years of trouble -free -service. REFERENCES 1.
