Socket Welded Elbow

Name: Socket Welded Elbow
Brand: Cangzhou Silver Valley technology Co., LTD

A socket weld elbow is a type of forged steel pipe fitting designed to change the direction of fluid flow in piping systems. It features a socket into which the pipe is inserted and then welded around the joint, providing a strong, leak-proof connection.

What is Socket Welded Elbow？

A socket welded elbow is a type of pipe fitting used to change the direction of flow in a piping system. It is designed to be connected to pipes using socket welding, a process where the pipe is inserted into a recessed area (socket) of the fitting and then welded around the joint. Socket welded elbows are commonly used in small-diameter piping systems and applications where high strength and leak resistance are required.

Standards of Socket Welded Elbow:

Socket welded elbows are manufactured according to industry standards, such as:

ASME B16.11: Covers forged steel fittings, including socket welded and threaded types.

MSS SP-79: Covers socket welding reducer inserts.

MSS SP-83: Covers socket welded and threaded unions.
