Minimizing wall thickness variation in seamless tubing

Seamless tube typically is manufactured on a two-roll piercer mill. In some cases this step alone is sufficient to produce tube that satisfies the customer's requirements. However, if wall thickness consistency needs further improvement after piercing, a tube producer can use additional equipment and process steps.
