Patent ID: 6892559

Claim:
A method for manufacturing a tube made of a non-ferrous material, comprising: feeding a tube billet in a predetermined feeding direction through a first working station and a second working station, wherein the second working station is downstream of the first working station with respect to the feeding direction of the tube billet and the second working station is so located relative to the first working station that simultaneously a first length segment of the tube billet is located in first working station and a second length segment of the tube billet is located in the second working station and a length segment of the tube billet that leaves the first working station substantially immediately enters the second working station, working the tube billet in the first working station so that mainly owing to deformation resistance, the temperature of the tube billet under operation rises up to the recrystallization range, at least on the working spot, working the tube billet in the second working station, and keeping at least the first and second length segments of the tube billet in non-oxidizing conditions.
