Abstract

One aspect of the invention concerns a steel tube drawing process in which a hot rolled seamless steel tube (10) of relatively large outside diameter and wall thickness is drawn down to a smaller outside diameter and wall thickness. The process of the invention comprises at least one drawing stage in which the tube (10) is located over a mandrel (24), the tube (10) is induction heated and drawn over the mandrel (24) and through a drawing die (22) which reduces the outside diameter of the tube, and the drawn tube is thereafter cooled. Another aspect of the invention concerns an apparatus which is used in the process.
