What is the continuous rolling process for straight seam steel pipes

First, what is the continuous rolling process for straight seam steel pipes?

The continuous rolling process is used for the continuous rolling and diameter reduction of steel pipes. Continuous rolling is a process in which the steel pipe and mandrel move together in multiple stands. The deformation and movement of the steel pipe are simultaneously affected by the rolls and the mandrel. The mandrel can be freely floating, meaning it moves forward entirely driven by the metal, or it can be restricted, meaning the mandrel is given a speed and its free movement is limited. During the process, the mandrel, rolls, and steel pipe are connected as a whole. A change in any component will cause a change in the state of the entire system. Continuous rolling theory studies the interrelationships between them.
