What is Forged Coupling?
Forged coupling is a high-strength pipe fitting used to connect two sections of pipes in a straight line. It is mainly divided into two forms: Full Coupling, with both ends having sockets or threads, used to connect two pipes; And half coupling, with one end as a socket or thread and the other end as a flat butt welding end, is commonly used for direct welding on container walls or large diameter pipelines as a branch connection port for small diameters.

What is Socket Weld Connection?
Socket welding is a reliable connection method designed specifically for high-pressure, small-diameter pipelines. During construction, insert the end of the pipeline into the socket of the pipe fitting, and reserve an expansion gap of about 1.5mm between the pipe end and the bottom of the socket. Then, perform corner welding on the outside of the pipe fitting. This connection method has high strength, good airtightness, and can ensure the relative smoothness of the internal flow channel of the pipeline. It is widely used in industrial fields that have strict requirements for sealing and pressure bearing capacity.
