Socket Weld Flange SW Flange

Socket welding flange refers to the flange where the end of the pipe is inserted into the flange ring step, and the pipe end and the outside are welded. Socket-weld flanges are typically used on smaller sizes of high pressure pipes. There are two types with neck and without neck. The flange with neck pipe has good rigidity, small welding deformation and good sealing performance. It can be used in occasions where the pressure is 1.0~10.0MPa. Type B flanges for vessels are also socket welding flanges, which are used in occasions with higher sealing requirements. When designing, the socket welding flange can be checked according to the integral flange. The size is up to 3", the pressure is up to 1500#.

We HT PIPE is the manufacture that provide all kinds of  steel flanges like Socket Weld Flanges, Blind Flanges, Plate flat Flanges, Weld Neck Flanges, Slip On Flanges, and so on, and also other special flanges according to the client's requirement.
