ASTM A335 P22 Alloy Steel Solid Fin Tubes With 11 - 13CR Fins For Power Generation
ASTM A335 P22 is a chromium-molybdenum (Cr-Mo) alloy steel pipe with a generally uniform wall thickness, designed specifically for high-temperature and high-pressure applications. It is widely used in power plants, oil refineries and petrochemical industries,etc. due to its excellent strength, corrosion resistance and high-temperature oxidation resistance.
| Advantages |
| High-Temperature Strength & Creep Resistance: Maintains mechanical strength under prolonged heat exposure.1250°F [675°C] |
| Good Oxidation & Corrosion Resistance:2.25% Chromium (Cr) content provides resistance to Oxidation (scaling) in steam and flue gas environments / Sulfidation in refinery and petrochemical processes |
| High Pressure & Stress Resistance:Suitable for high-pressure steam lines, power plant piping, and refinery heaters. |
| Cost-Effective Compared to Higher Alloy / Thermal Fatigue Resistance / Compatibility with Finned & Bent Configurations |

Role of A335 P22 Alloy Steel Solid Fin Tubes For Power Generation
ASTM A335 P22 alloy steel solid fin tubes play a critical role in enhancing the efficiency, durability, and performance of power generation project, particularly in boilers, heat exchangers,furnaces and waste heat recovery units. Their especial design (finned surface) and material properties (high-temperature strength, corrosion resistance) make them suitable for demanding thermal applications.
Applications For Power Generation
A. Boiler Superheaters & Reheaters
B. Heat Recovery Steam Generators (HRSGs)
C. Economizers (Feedwater Heaters)
D. Waste Heat Boilers (Biomass, Coal, Gas Plants)
