Structure and working principle of Hydraulic pipe bending machine
The electric pipe bending machine is composed of electric oil pump, high pressure oil pipe, quick joint, working cylinder, plunger pump, bending part. The high pressure oil out put from the electric oil pump, through the high pressure oil pipe into working cylinder, high pressure oil push the plunger pump in the cylinder, forming the pushing force, then through the bending part to bend the pipe.


The heat-induction pipe bending process was originally used during World War II to harden surfaces of gears and ball bearings. The pipe bending industry uses the heat-induction pipe bending process by placing an induction coil around the pipe to be bent. The induction coil heats a narrow, circumferential section of pipe to a temperature of 800 to 2,200 F, depending on the material type. At proper pipe bending temperature, the pipe passes through the induction coil at a slow, gradual rate as the bending force is applied.

After bending occurs, the heated area is quenched by a water or air spray. This pipe bending process produces a quality product, however its typical cost is higher than other methods. Pipe sizes up to 48" outside diameter and larger are commonly bent by this pipe bending method for applications including power plants, highway road signs and petroleum pipelines.
