Applications of ASTM A387 Grade 22 Class 2 Steel Plate

ASTM A387 Grade 22 Class 2 steel plate  is a chromium-molybdenum alloy steel plate specifically designed for high-temperature and high-pressure environments. It is widely used in critical industries such as petrochemicals, energy and power generation, pressure vessel manufacturing, and offshore engineering. Its exceptional properties make it a core material for equipment manufacturing under extreme operating conditions.
Petrochemical Industry
Equipment Manufacturing: Used for critical equipment such as high-temperature and high-pressure reactors, heat exchangers, separators, hydrogenation reactors, and catalytic cracking units. Its hydrogen corrosion resistance enables it to effectively withstand hydrogen-containing environments, preventing hydrogen embrittlement or hydrogen-induced cracking.
Piping Systems: Suitable for pipelines transporting high-temperature and high-pressure oil, gas, and refined products, ensuring safe transmission of media under elevated temperatures.
Energy and Power Generation
Boiler Components: Serves as a core material for boiler components such as steam drums, superheaters, reheaters, and steam pipelines, capable of withstanding long-term exposure to temperatures above 600°C and high-pressure steam.
Power Generation Equipment: Used in manufacturing high-temperature components like gas turbines and steam turbines, ensuring the stable operation of power generation systems.
Pressure Vessel Manufacturing
Hydrogen-Service Equipment: In hydrogen storage, transportation, and hydrogenation reaction units, its resistance to hydrogen corrosion significantly extends equipment lifespan.
Chemical Vessels: Applicable to reactors, storage tanks, and other equipment operating under harsh conditions involving strong acids, alkalis, high temperatures, and high pressures.
Offshore Engineering Applications
Offshore Platforms: Used for manufacturing high-temperature and high-pressure pipelines and pressure vessels for offshore drilling platforms and FPSOs (Floating Production, Storage, and Offloading units), withstanding seawater corrosion and extreme environments.
Deep-Sea Equipment: In deep-sea oil and gas exploitation, its corrosion resistance and high-temperature strength meet the complex demands of high-pressure and low-temperature deep-sea conditions.
