Shanghai Zhucheng manufacture specilized in forged steel fittings. Carbon steel is heated to molten temperatures and placed in the dies. The heated steel is then machined into the forged steel pipe fittings.There are various types of forged pipe fittings, such as Socket Weld Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, Union and Sockolet; 

 

A Socket Weld Fittings is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. Once correctly inserted, fillet type sealing welds are applied to join the pipe to the fitting.

Different from buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally, for piping whose nominal diameter is NPS 2 or smaller.

 

These fittings are commonly called SW pipe fittings that include elbows, tees, cross, caps, coupling and union.

 

Socket welds can be used to change the direction of travel for pipe networks as well as join pipes at different angles and of different diameters.

 

Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.

According to the production method, it can be divided into pushing, pressing, forging, casting, etc.

According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).
