Socket welding flange

Socket welding flange

What is socket welding flange?

Socket welding flange is typically used on smaller sizes of high pressure pipes.

It refers to the pipe end inserted into the flange ring ladder, welded at the pipe end and outside the flange. The flange has good rigidity, small welding deformation and good sealing that can be used for the occasions of 1.0~10.0MPa pressure.

Flange connection:

Socket weld flange connection is an important connection mode for pipeline construction, which is the two pipes, pipe fittings or appliance materials, respectively fixed on a flange plate, between the two flanges, plus flange pad, fastening together with screws, to complete the connection.

Socket welding flanges are divided into threaded connection flanges and welded flanges. Low pressure small diameter wire flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connecting screw diameter and number are different. Flange connection is easy to use and can bear greater pressure. It is widely used in industrial pipes.
