US Standard F22 Alloy Steel Flange, Specially Designed for High Temperature and High Pressure

ASME ASTM A182 F22 (2.25Cr-1Mo) alloy steel flanges feature excellent high-temperature strength, creep resistance and hydrogen corrosion resistance. They are stably suitable for high-temperature working conditions below 550°C, and can reliably handle harsh environments such as hydrogen service, sulfur-containing media and high-temperature steam, making them an ideal material for high-temperature, high-pressure and corrosive applications.

These products are widely used in four core industries: thermal power, petrochemical, coal chemical and oil & gas. They are applied to key parts including boiler main steam pipelines, hydrogenation units, furnace pipelines and oil and gas gathering and transportation systems. With compact structure, high pressure resistance, heat resistance and reliable sealing performance, they ensure long-term safe operation of piping systems and are an optimal choice for connections in high-temperature industrial pipelines.
