Carbon steel SW flange refers to the flange that is inserted into the flange ring ladder at the end of the pipe and welded at the pipe end and outside. There are two kinds of flanges with neck and without neck. The pipe flange with neck has good rigidity, small welding deformation and good sealing performance. It can be used for occasions with pressure of 1.0 ~ 10.0MPa.

Carbon steel SW flange also includes type B flange for vessels, which is used in occasions with high sealing requirements, and is mainly used for pressure pipes above 4kg. For the pipes to be connected, install a flange, add a gasket between the two flanges, and then fasten them with bolts.
Carbon steel SW flange is widely used in chemical industry, construction, water supply, drainage, petroleum, fire protection, electric power, aerospace, shipbuilding and other basic projects.
