Socket Weld Coupling

The Socket Weld Coupling is a key forged fitting in medium- to high-pressure piping systems for straight connections between pipes of the same diameter. It features an integral forged structure with socket-type ends. After inserting the pipe ends into the sockets, the connection is secured via fillet welding, delivering high connection strength and reliable sealing performance.

Widely applied in industries such as petroleum, chemical, oil & gas transportation, electric power and energy, metallurgy, shipbuilding, pharmaceuticals, heating supply, and long-distance pipelines. Suitable for harsh working conditions involving steam, oil products, gases, flammable and explosive substances, as well as corrosive media. It serves as an economical and efficient solution for pipeline extension and transition connections in medium- and low-pressure piping systems.
