Connection Types Of Pipe Fitting

Butt Weld Fittings

This is a type of weld that is used to bind two or more pieces together. Alternatively, it refers to the process of welding two or more parts together, which includes the weld, the fusion zone, and the heat impacted zone. A high-temperature heat source is used to generate the welded connection in fusion welding. Such as Eccentric Reducer, Concentric Reducer, 90 Deg Elbow and other pipe fittings adopt this connection method.

Socket Weld Fittings

Socket Weld Fittings are commonly used to connect fittings in piping systems. The connection method is to insert the pipe into a sleeve of appropriate size, and then weld the joint of the sleeve and the pipe to connect. This type of connection is usually used for small-bore pipes and is suitable for high-pressure or high-temperature environments. Commonly used in Socket Weld Cross, Socket Weld Tee and other pipe fittings.
