Manufacturing process of Galvanized Elbow

Elbow is a kind of pipe fitting used for pipe turning. It has 90 degree elbow, 45 degree elbow and so on. Galvanized Elbow can be manufactured according to the needs of the project. The manufacturing process of elbow with different materials and different pressures is also different.

The forming process of seamless elbow commonly used in our factory includes hot pushing, stamping, extrusion, etc.

We are Elbow Fitting Supplier

The hot push elbow forming process is a process in which a special elbow pushing machine, a core die and a heating device are used to make the blank sheathed on the die move forward under the push of the pushing machine and be heated, enlarged and bent during the movement. The deformation characteristic of the hot push elbow is to determine the diameter of the tube blank according to the law that the volume before and after the plastic deformation of the metal material is constant. The diameter of the tube blank used is smaller than the diameter of the elbow. The deformation process of the blank is controlled by the core die, so that the metal compressed at the inner arc flows and compensates to other parts thinned due to the expansion, so as to obtain the elbow with uniform wall thickness.
