A182 F347 Stainless Steel Pipe Flange

Stainless Steel 347 Flanges range from ½ inches to 48 inches in size and have different specifications and standards to govern the dimensions. The material is a columbium stabilized austenitic stainless steel. The specifications are ASTM A182 and ASTM A240. The A182 F347 Stainless Steel Pipe Flange is made up of the F347 material that has 18% chromium, 10% nickel, carbon, silicon, sulfur, phosphorus, 2% manganese with cobalt and titanium for stabilization.

The UNS S34700 Pipe Flange has 515MPa minimum tensile strength, 205MPa minimum yield strength and 1454 degrees Celsius melting point. The flanges come in different functional types such as the SS 347 Blind Flange, lap joint flange, weld neck flange and many other types. Each of the different types have specific use cases. The blind flange is used to close a pipeline and used at the end of a pipe. There are different types according to the faces as well. The Stainless Steel F347H Plate Flange, raised face and ring type joint are the main types of faces to these flanges. The pressure classes of these flanges vary with the dimensions. There are pressure classes 150 through 2500 for these flanges. These flanges are used in high pressure and high temperature services. The BS 10 Stainless Steel F347 WNRF Flange is a welded neck raised face flange. The welded neck allows for better welding connection where the raised face allows more space for bolt holes and welding as well.
