Learn more about theoretical bursting pressures for stainless steel pipe. Stainless steel raised face weld neck flanges, are used to block the end of a pipe system or valve. The raised face is engineered to concentrate more pressure to a smaller area on the flange, which provides an increased containment capability at higher pressures. The weld neck flange is also engineered to match the inside diameter (ID) of the joining pipe. This flange is ideal for high pressure, high heat and sub zero temperature applications. This flange is inserted and welded to the joining pipe.
