Process
How Does an Induction Pipe Bending Machine Work?
01. Pipe Preparation
The pipe is checked for diameter, wall thickness and material grade, marked for the bend, and loaded onto the machine bed.
02. Machine Setup
The clamps, bending arm and induction coil are set for the required bending radius and angle, and the bending program is loaded on the PLC.
03. Induction Heating
An induction coil heats a narrow ring of the pipe to bending temperature, while the rest of the pipe stays cold and holds its shape.
04. Controlled Bending
The hydraulic cylinders push the pipe slowly through the coil while the arm turns, so only the heated ring bends to the set radius.
05. Cooling
A water spray just after the coil cools the bent section at once, which fixes the radius and limits ovality and wall thinning.
06. Inspection
The finished bend is checked for radius, angle, ovality and wall thickness against the drawing.

Induction Pipe Bending Machine FAQs
An induction pipe bending machine heats a narrow ring of the pipe with an induction coil, pushes the pipe through the coil while a bending arm turns, and cools the bent section with water. This gives smooth, one-piece bends with low ovality and controlled wall thinning.
