Socket weld flange is a flange with one end welded with steel tube and the other end connected with bolts. It is suitable for connecting pipe with small diameter, high pressure and high temperature,

usually used in the pipelines with PN≤ 10.0mpa and DN≤40.

Socket weld flanges are counter-bored to receive the pipe earlier than being fillet welded. The bore of the pipe and flange are both the equal to grant exact float characteristics. Stainless steel socket weld flanges are oxidation resistant and promote better weldability and fabricability.
