Socket flange refers to the flange that the end of the pipe is inserted into the flange ring ladder and welded at the pipe end and outside. There are two kinds with and without neck.
The pipe flange with neck has good rigidity, small welding deformation and good sealing performance. It can be used in occasions with pressure of 1.0 ~ 10.0MPa. B-type flange for container also belongs to socket welding flange, which is used in occasions with high sealing requirements. During design, socket welding flange can be checked as integral flange.
Materials are divided into:
