Abstract

In the manufacture of seamless metal tubes by a cross-roll helical rolling process, or by a press piercing process, shells being worked are subjected to outside-diameter reduction by means of a mill having three or four rolls, without the use of internal sizing tools or a mandrel, so that the wall eccentricity is significantly improved. <IMAGE>
