In a process in which pipe sections are advanced longitudinally through a treatment zone while being rotated about a longitudinal axis, the pipe sections are supported as they emerge from the treatment zone in a manner which does not damage their treated surfaces. The pipe sections are coupled together by coupling members which provide rigid circumferential support surfaces between adjacent pipe section ends. A shuttle carriage, which can reciprocate between first and second limit positions, has a support assembly which can be raised and lowered into and out of supporting engagement with each successive coupling member to support the coupled ends of a pair of pipe sections over a predetermined distance upon leaving the treatment zone.
