Abstract

The method is used for bending a metal pipe (1), or rod. The pipe is made to pass through annular heating device (5), where a short portion of the pipe is heated, and then through adjacent cooling device (6). The forward end or the desired portion of the pipe is then made to pass through a curved path by means of a rotatable (8) arm (7) to which the pipe is secured (9). A bending moment acting on the pipe causes plastic deformation as it passes through the heating zone, and the clamp arm (7) causes controlled longitudinal movement at the start and/or the end of the bending operation.
