Socket welding flange refers to the pipe end inserted into the flange ring ladder, welded at the pipe end and outside the flange. There are two kinds with and without neck. The flange with neck pipe has good rigidity, small welding deformation and good sealing performance. It can be used for occasions with pressure of 1.0~ 10.0mpa. Container type B flange is also a socket welding flange, used for high sealing requirements. During design, socket welding flange can be checked according to the integral flange.
