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.

No leaks, no fin damage, performance consistent. Heat transfer hasn't dropped, so fouling doesn't seem to be a problem yet.

For power plant boilers, especially in industrial settings like ours, these tubes work. Good heat transfer, holding up well.
