What is F22 Flange?
Alloy Steel F22 Flanges come in different specifications and classes. A182 F22 is made up of chromium molybdenum alloy. The alloy is designed to work under high pressure and high temperature conditions. A182 Gr F22 Flanges have very high chloride corrosion resistance and can withstand harsh corrosive environments such as in the marine industry and in paper and pulp industry. ASTM A182 Grade F22 Flanges also hold excellent resistance against sulfuric acid which makes them suitable for chemical industries where sulfuric acid lines have to be connected together. ASTM A182 F22 Pipe Flanges can be delivered in different forms and shapes such as, raised face, welded neck, slip on, blind face and others.
