ASTM A182 Grade F22 Alloy Steel Flanges Manufacturers

Alloy Steel F22 Flanges are made from carbon steel, which contains elements like carbon, manganese, silicon, phosphorus, sulfur, molybdenum, and 4% chromium. Delta Steel manufactures and supplies ASTM A182 F22 alloy steel flanges in various types, shapes, and sizes. These flanges have a minimum yield strength of 205 MPa, a minimum tensile strength of 415 MPa, and an elongation rate of 20%.

There are three classes of flanges in this material: Class 1, Class 2, and Class 3. Class 2 flanges are less common but have better mechanical properties than Class 1. Class 3 flanges are the strongest and rarest. These flanges are covered under the ASTM A182 specification, which applies to forged low-alloy and stainless steel piping used in high-pressure applications. They come in types like slip-on, blind, weld neck, and socket weld, with sizes ranging from ½ inch to 48 inches in diameter and various wall thicknesses. The pressure ratings go from Class 150 to 2500, with pressure numbers (PN) ranging from PN6 to PN64. Flanges can have different faces, such as flat, raised, or ring-type joints.

The SA 182 Gr F22 slip-on raised face (SORF) flanges are designed so that pipes can easily slip onto them, allowing for convenient connections. The raised face provides better grip, space for welding, and bolt holes. SA182M Chrome Moly Gr.F22 blind flanges are widely used in industries like petroleum, petrochemical, offshore and onshore drilling, gas processing, power generation, and heat exchangers.
