FIELD: working of metal. SUBSTANCE: method involves deformation of hollow billet in die pass by means of driven rollers of rotating casing, with outer diameter of material to be deformed exceeding diameter of die pass. Die operating profile and roller shape are chosen such that counteraction to relative motion of deformed metal in zones of contact is minimum. EFFECT: increased efficiency of method and high quality of tubes and enclosures. 3 cl, 3 dwg
