Pipe induction bending

Hei Yan Group is a induction bending machine company specilizing in manufacturing pipe induction bending,hydraulic elbow machine,tee form machine etc.

Process on Pipe induction bending

1 Installation of induction coil

  Install sutable induction coil onto water pipe's transformer,then connect with water  pipe and be sure no leakage.

2 Load material

  Load material from the end of pipe induction bending,pipe should be over induction coil.First adjust height of conveyor idler and make pipe in center of the hole.Transformer coils have equal distance around pipe,then turn back pushing board and screw pipe and ready to bend.

3 Adjust radius of pipe induction bending

  Loosen bolt of arm axes,set up control pump,control oil vat will push arm axes center.Screw bolt of arm axes and choose suitable coils to tight pipe,finally screw arm pole bolt.

4 Bending

  Turn on power,water pump,induction heater,control pump,main pump,electric-magnetism speed governor,adjust power of frequency and heat material up to 800 degree,press push switch,adjust electric-magnetism speed governor to suitable pushing speed of pipe,note clearance of pipe and coil when pushing.When bending is Ok,press stop as well as 0 operate on induction heater,then press turn back to relax push force,press main stop button to shut down oil pump,shut down induction heater,open idler clamp and cut bend down from pipe induction bending machine.

Pipe induction bending advantage

Induction bending does not require any sand filling or internal mandrels. The bending times are considerably less than in fire bending or weld fabrication, making the process cost effective.
The quality of the bends with respect to surface finish are equal to that of cold bending, better than fire bending, and in the case of ovality and wall thinning, are superior.
As the process eliminates the need for welded or mechanical joints between bends, the integrity of the finished pipe work is higher than in any other process.
