Features of ASTM A335 P22 Pipes
Outstanding Creep Resistance
Excellent Oxidation & Anti-Scaling Capacity
Hydrogen Attack & Sulfidation Resistance
Stable Thermal Conductivity & Low Thermal Fatigue
ASTM A335 is standard of seamless ferritic alloy-steel pipes with nominal wall and minimum wall thickness for high-temperature service. ASTM A335 P22 alloy steel pipes are essential components in high-temperature and high-pressure applications, particularly in power plants, refineries, and petrochemical industries.P22 exhibiting excellent long-term creep rupture strength at temperatures up to 565°C, it is suitable for waste heat boilers, superheaters, reheaters, and air-cooled condenser (ACC) manifolds under high-pressure superheated steam (10–16 MPa) in power plants.
Application in Power Plant
Ideal for equipment with clean flue gas / cooling air without heavy sulfur corrosion:
Combined-cycle HRSG evaporators, economizer sections, waste heat recovery coils
Air-cooled condensers (ACC) for thermal power plants (dry cooling island)
Low-temperature reheater loops, boiler flue gas heat exchangers
Steam auxiliary coolers, feedwater preheaters
In short, ASTM A335 P22 high-frequency resistance welded serrated finned tube with carbon steel fins, metallurgically bonded to enhance turbulent heat transfer, exhibiting excellent high-temperature creep resistance and steam oxidation resistance. It specifically designed for combined cycle waste heat boilers, air-cooled condensers, and waste heat recovery systems in thermal power plants, balancing high heat exchange efficiency with overall project cost.
