The induction bending equipment is composed of four basic components:
1.- A bed
2.- Radial arm
3.- Induction system
4.- Cooling system
A clamp, movable on the radial arm, and the bed of the machine,
movable on rails, are set to obtain the required radius. A straight
length of pipe is placed in the machine bed and the front tangent
is clamped on the radial arm.
The induction heating system heats a narrow circumferential zone
around the pipe to the appropriate bending temperature. When this
temperature is reached the pipe is continuously moved through
the heating ring while a bending movement is applied to the heated
area.
After passing through the ring, the pipe may be either forced
or naturally cooled, as required by the applicable qualified bending
procedure.
