Abstract
In a plug mill following a Mannesmann piercing mill on a seamless tube production line, a method whereby the rolled hollow shell which has been subjected to the first rolling pass is automatically rotated about its longitudinal central axis by an angle of about 90 DEG while it is being returned to the inlet V-table of the plug mill for the second rolling pass.
