ASTM A335 P22 Seamless Alloy Steel Boiler Pipes For Refineries Projects
ASTM A335 This specification covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. ASTM A335 P22 is a chromium-molybdenum (Cr-Mo) alloy steel pipe for widely using in high-temperature and high-pressure applications, particularly in power plants, refineries, and petrochemical industries,etc.
Chemical Composition max%
A balanced mix of alloying elements for strength, heat resistance, and corrosion resistance (Cr enhances oxidation and corrosion resistance at high temperatures; Mo improves creep strength and high-temperature stability)
Mechanical Property
P22 pipes have excellent tensile strength, yield strength, and hardness. With high creep & oxidation resistance,Ideal for prolonged high-stress conditions;with weldability & durability, can easier to fabricate compared to higher-grade alloys.
Applications
Power Generation (Boiler Systems) Superheaters & Reheaters ; Steam Lines ; Heat Exchangers & Condensers
Oil & Gas Industry Refinery Piping ; Petrochemical Plants ; High-Pressure Pipelines
Chemical Processing High-Temperature Reactors ; Process Piping
Other Industrial Applications High-Temperature Service in Manufacturing ; Nuclear Power Components
