There are three basic processes for hot rolling seamless pipe production line :
â‘ Punch the ingot or billet into a hollow thick-walled rough pipe on the piercing machine.
â‘¡Stretch the rough pipe to form a rough tube close to the wall thickness of the finished product.
â‘¢Roll it into the required finished tube on the finishing mill.
