ABSTRACT:
In a process for reducing the outer diameter and wall thickness of an essentially cylindrical hollow tube blank by rolling, the front end of the tube blank is introduced into a rolling mill. To prevent piping defects during rolling and to obviate other disadvantages of conventional processes, the diameter and/or the wall thickness of the trailing end portion of the tube blank is reduced before the trailing end portion is introduced into the reduction zone of the rolling mill.
