We are prominent manufacturers of Inductor and Cooling Rings for Pipe bending machines. The Inductor Ring assembly consist of Inductor Ring, Quench ring and Air Ring for Precise heating and Controlled temperature cooling.

The induction bending process is used for the forming of pipes. In this process, the front end of the pipe to be bent is firmly clamped in a bending arm.

A narrow zone of the pipe in the bending area is heated by means of a ring-shaped inductor with a precisely controlled temperature control.

After heating, the pipe is pushed through the inductor at a constant velocity. In this process, the front clamped end of the pipe has to follow the circular movement of the bending arm. The forming takes place in the zone heated by the inductor where the forming resistance is lower than in the adjacent cold sectors.

The forming zone continually moves along the length of the pipe in line with the projection velocity of the pipe, whereby the cold areas on both sides of the heated zone have a stabilizing effect in the forming and a bending with no tools being used internally. This gives rise to pipe bends with high forming precision and narrow tolerances.

We offers a complete line of Inductor Ring Assemblies ranging from Pipe Dia 4”(100mm) to 55”(1400mm).
