What is the maximum diameter of large diameter seamless steel pipe? The production method of large diameter seamless steel pipe is usually hot rolled seamless steel pipe and hot expanded seamless steel pipe. Due to the limitation of process, the size of the seamless steel pipe is larger, with a diameter of 325-1220 mm and a wall thickness of 200 mm. Cross rolling or drawing is used to enlarge the diameter of tube. In a short period of time to make the outer diameter of steel pipe larger, can produce non-standard, special types of seamless pipe, and low cost, high production efficiency, is the development trend of international pipe rolling field.
