Tube mills produce pipe and tube by taking a continuous strip of material and continuously roll forms it until the edges of the strip meet together at a weld station. At this point, the welding process melts and fuses the edges of the tube together and the material exits the weld station as welded tube. Basic components include an uncoiler ...

rotary tube piercing (RTP) mills, but there are different configurations depending on the number and shapes of the director rolls and guiding devices. Piercing mills that count with two rolls are the most extended ones. In addition, they are sorted in Diescher's or Stiefel's mills when their guides are discs or shoes respectively [2].

The piercing mill features two specially contoured work rolls which are driven in the same direction of rotation. The axes are inclined by approximately 3° to 6° in relation to the horizontal stock plane. The roll gap is generally closed by a non driven support roll at the top and a support shoe at the bottom.

The use of screwrolling mills, as compared with piercing in the press, makes it possible to increase the productivity and obtain shell with thinner walls. The higher degree of prestraining in the piercing mill substantially extends the capabilities of push benches both in the lengths of obtained pipes and in their assortment.
