Socket joint is a type of pipe connection made by forging round steel or steel ingots and machining them. It is made of stainless steel and consists of three parts: nut, cloud head, and flat joint. The connection forms include socket welding and threaded connection. Its connection forms include socket welding and threaded connection, where socket welding is fixed by inserting steel pipes into socket holes. This product has both equal diameter and reduced diameter varieties, and its structure includes components such as sockets, sockets, and sockets. The design focuses on improving operational convenience and leak prevention performance. The socket joint consists of three parts: nut, cloud head, and flat joint. The connection forms include socket welding and threaded connection. Socket welding is the process of inserting steel pipes into socket holes for welding, hence it is called a “socket joint”. As of 2025, the main manufacturing standards include ASME B16.11 and MSS SP 83. It can be widely used in different diameter pipelines, water meters, valves and other scenarios.
