ASTM A182 / ASME SA182 600LB F304 / 304L Stainless Steel Socket Welded Flange
Stainless steel socket welded flange is a tubing fitting used to connect pipes, usually for applications under high pressure or high temperature conditions. It has a raised edge for connection to the end of a pipe and a hole for threading or welding. The orifice is designed to fit directly into the end of the pipe on the pipeline, and the connection is usually secured using a welding method.
This type of flange is usually made of stainless steel and therefore offers excellent resistance to corrosion and high temperatures. The design allows the flange to be attached to the pipe end by welding or threading, providing a reliable seal.
