Apparatus for continuous heat treating advancing continuously formed pipe in a restricted space

摘要

An apparatus for continuous heat treating advancing continuously formed pipe in a restricted space with minimal deformation of the pipe during the heat treatment comprising a pipe feeder; curved rollers for receiving the pipe and advancing the pipe there around. A heat chamber for housing the curved rollers. A heat source for providing heat to the heat chamber and the pipe. A first deforming element for deforming the pipe into a curve for following the curve rollers and for directing the pipe to transverse across the rollers as the pipe is advanced around the rollers. A second deforming means for receiving and deforming the said pipe as it exists from the rollers into a substantial straight line and a take-up roller for receiving the pipe as it comes through the second deforming means.
