Abstract

For induction bend forming a compression-resistant pipe (1) having a large wall thickness and a large diameter, the pipe (1) is vertically compressed in a press unit (50) before it is introduced into an annular inductor to heat it and a cross-section in the shape of a lying oval is imposed onto the pipe (1) in said press unit. In addition, at least during an interval of the pipe bending process a temperature profile with a lower temperature on an outer surface of the bend and a higher temperature on an inner surface of the bend is set by means of a transverse displacement of the inductor relative to the pipe (1).
