Large diameter heavy wall seamless steel tube
The main production processes of large-diameter seamless steel pipes are hot-rolled large-diameter seamless steel pipes and heat-expanded-diameter seamless steel pipes. The maximum specification of hot-expanded seamless steel pipes is 325mm-1220mm and the thickest is 200mm. It is used for steel pipes with relatively low density but strong shrinkage. A waste tube finish rolling process in which the diameter of the tube is enlarged by the cross-rolling method or the drawing method. In a relatively short period of time, thickening steel pipes can produce non-standard and special types of seamless pipes, with low cost and high production efficiency, which is the development trend of the international pipe rolling field.
