METHOD FOR INDUCTION BEND FORMING A COMPRESSION-RESISTANT PIPE HAVING A LARGE WALL THICKNESS AND A LARGE DIAMETER AND INDUCTION PIPE BENDING DEVICE

摘要

The pipe (1) is compressed vertically in a pressing unit (50) prior to introduction into the inductor (20), such that a cross-section of the pipe (1) is forced into the shape of a lying oval, and a temperature profile with a lower temperature at an outer side of the bend (3.2) and with a higher temperature at an inner side of the bend (3.1) is set at least during a portion of the pipe bending process by means of a transverse movement of the inductor (20) relative to the pipe (1).
