ASTM A182 F44 Uns S31254 Smo 254 Flanges

SMO 254 Flanges belong to the ASTM A182 specification with sizes ranging from ½ inches to 48 inches. There are different standards to govern the dimensions such as ASME, ANSI, DIN and other international standards. The UNS S31254 Pipe Flange is made under different production types such as the forged, screwed, threaded and plate flanges. There are also different functional types such as slip on flanges, lap joint flanges, orifice flanges, welded neck flanges and blind flanges. The blind flanges come in different types such as the SMO 254 Spectacle Blind Flange as well. Each different type of flange has a purpose to serve in an application. The face type of the flanges vary as well.

There are raised face, flat face and ring type joint face types of flanges ranging from pressure classes 150 through 2500. The 6mo Plate Flange and other flanges are made from a chromium, nickel, molybdenum alloy. The material has 19% chromium, 17% nickel, 6% molybdenum with carbon, manganese, silicon, copper, sulfur and sulfur in it. The different types of flanges such as the 254 SMO Slip on Flange have good corrosion resistance due to the composition. The flanges are also stronger than the ordinary stainless steel flanges with 650MPa minimum tensile strength, 300MPa minimum yield strength and 35% elongation rate. The UNS S31254 Weld Neck Flange is preferred in welding applications. These flanges can hold the pipe in place during welding. The material has up to 1390 degrees Celsius melting point so that it could be used in high temperature and high pressure applications such as power generation, heat exchangers, boiler and petrochemical industrial applications.
