Pipes with bends and curves are not only indispensable in the petrochemical and oil and gas industries, but also in the construction of power plants, tanks and pipelines. The induction bending technology used in these fields is an efficient process in which round or rectangular tubes, T-beams and profiles are heated using a medium-frequency inductor and formed into the predetermined shape.

The first induction bending machine was developed and delivered by AWS Schäfer Technologie as early as 1986. Since that time our engineers have continually developed and improved the process which today enables even the most demanding bending tasks to be performed efficiently. With a total of six registered patents we are the global technology leader in induction bending machines.
