Manufacturing process of Welded Elbow

Elbow is a kind of pipe fitting used for pipe turning. It has 90 degree elbow, 45 degree elbowand so on. It 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 elbowcommonly used in our factory includes hot pushing, stamping, extrusion, etc.carbon steel Degree Elbow

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.

The tube blank equal to the outer diameter of the elbow is used for the stamping of the elbow, and the press is used to directly press the elbow in the die.
