Induction pipe bending to ASME B16.49
The induction bending process was originally used during World War II to harden gear and ball bearing surfaces. Today, induction bending enables the bending of large pipes, including square and rectangular tubes.
To create induction bends, induction pipe bending experts place an induction coil around a pipe. The coil heats a narrow section of pipe to 800 to 2,200 degrees Fahrenheit, depending on the material type. Once the proper temperature is reached, the pipe slowly passes through the coil as the bending force is applied. After the induction bends are formed, the heated area is cooled by a spray of water or air.
Creating a precise induction bend requires extensive induction bending expertise. Compared to cold forming methods, Meets ASME B16.49 & TPA-IBS-98induction bending minimizes deformation of the material and distortion of the cross-section even when tight radius bends are required. Pipes formed with induction pipe bending by Tulsa Tube Bending can be found in power plants, highway road signs and petroleum pipelines.
