The round billets are pierced using a cross roll piercer. The piercing mill presses the billet against a plug to pierce the billet, and then rolls the billet between rolls and the plug. The pierced billet or hollow tube is then roll reduced (hot or cold) to obtain the prescribed outside diameter and wall thickness. This process is used to make larger sizes of seamless pipe, typically 6 to 16 ...

Piercing a seamless steel tube is a forging operation in which the metal is worked from the inside as well as the outside. We convert a solid bar into a hollow shell by displacing material over a mandrel during rotary rolling. This process results in a refined grain structure and uniform grain flow. Subsequent seamless tube processes include elongating to reach the desired wall thickness ...
