Following the piercing process, elongation and sizing operations are performed to further refine the pipe dimensions. Elongation involves elongating the pierced shell using a push bench or a stretch reducing mill. This process enhances the mechanical properties and reduces wall thickness variations. Sizing, which is done using a sizing mill, ensures accurate outer diameter and wall thickness according to specifications.
