Abstract

A metal pipe (T) is fed at a first speed into a space between delimited successive contiguous mechanical corrugators (34, 38), each of which turns around an axis coinciding with the axis of the pipe (a) and is disposed eccentrically with respect thereto and has a spiral inner corrugating surface with its axis (b, c) offset with respect to the axis of the pipe and a diameter greater than the diameter of the pipe. The corrugated pipe (TC) is extracted at a second speed lower than the first speed.
An appropriate coordination between the input speed, the output speed and the pitch of the spirals of the corrugating fixtures allows corrugated metal pipes with parallel annular ridges to be produced continuously.
