Induction bends manufactured to ASME B16.49 can be either made from seamless or welded pipes with or without tangent length by cold- or heat-forming process. Generally, heat-forming process is applied which utilizes the mid-frequency induction-bending machine. This process utilizes induction heating to heat a narrow band 360 deg around a pipe or cylinder at the point of bending as the pipe or cylinder is being pushed through the inductor coil at a constant velocity. After the material passes through the coil, it may be cooled by forced air or water spray, or it may be allowed to cool in still air. Bends in any producible wall thickness and diameter are covered.
