Precautions for making elbow

The elbow produced by the manufacturer is a kind of pipe fitting. The main use of the elbow is to connect the pipe into the pipe parts. According to the connection method, it can be divided into four categories: socket pipe fittings, threaded pipe fittings, elbow pipe fittings and welded pipe fittings.

In the commonly used elbow specifications, it has been replaced by hot push elbow, but in some elbow specifications, the wall thickness is too thin or too thick because the production quantity is relatively small.

Elbow products have special requirements to use the stamping production and manufacturing process. In the forming process of the stamping elbow, the caliber needs to be the same as that of the produced elbow, and the press is used to directly press the molding in the mold.

Stamping elbow is divided into cold stamping and hot stamping more stamping elbow material selection production and manufacturing process, stamping elbow production and manufacturing process is not as good as push elbow, quality appearance is not as good as the former, stamping elbow in the forming arc in the tensile state, there is no other parts of the excess metal compensation, so the wall thickness of the outer arc is about 10% thinner.

But because it is suitable for unit production and low cost, the manufacturing process of stamping elbow is suitable for small batch production of high pressure thick wall stamping elbow.
