Socket Weld Flange

Socket Weld Flange

Flanges for petroleum, chemical, and other industries

Socket weld flanges are flanges where the end of the pipe is inserted into the flange ring step and welded at the end and outside of the pipe. There are two kinds of flanges with and without neck. Necked pipe flanges have good rigidity, small welding deformation, and better sealing, and can be used when the pressure is 1.0~10.0MPa. B-type flanges for containers are also socket weld flanges, which are used in occasions with high sealing requirements. When designing, socket weld flanges can be calibrated as integral flanges.

Sealing surface form

Raised face (RF), concave-convex face (MFM), tongue and groove face (TG), ring joint face (RJ).
