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