5. Hot Rolled Tube Mill - Piercing press and push bench 

Following heating to forming temperature, blooms are placed in the circular die of a piercing press. A piercing mandrel then forms them into a thick-walled hollow shell with the closed bottom. The hollow shell passes to an elongator - with three rolls. The hollow shell is then elongated on the push bench, without reheating to between 10 and 15 times its incoming length, using a mandrel bar as the internal tool.
