Pipe Fitting Manufacturing Process

Connection Types Of Pipe Fitting

Butt Weld Fittings

This welding technique is utilized to unite two or more pieces, involving the weld, fusion zone, and heat-affected zone. Fusion welding employs a high-temperature heat source for creating the welded connection.

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.
