ASTM A182 F53 flange is a high-strength flange with a minimum tensile strength of 800MPa and a minimum yield strength of 550MPa. There are different types of flanges, such as slip-on flanges, socket welding flanges, forged flanges, blind flanges, reducing flanges and so on. YUHONG GROUP is a leading manufacturer and supplier of SA 182 F53 flange types in various sizes and shapes. Flanges can also be manufactured as threaded, threaded or forged types. The forged flange is made from one piece of raw material. These are also called cast flanges.

Dimensions and weights of Class 150 Flange

The face type of flange A182 F53 can also be different, such as flat, raise and ring joint flanges. Flat flanges have flat surfaces, which allows them to be used in narrow spaces, where raised flanges have many surfaces for bolting and welding connections. The ring joint flange is divided into two halves and welded to different pipe ends, and they are combined by welding to obtain maximum sealing. The diameters of ASTM A182 F53 and F55 range from ½ inch to 48 inches, and the pressure rating ranges from CL150 to CL2500.
