    Cold Pilger Rolling: Part One :: Total Materia Article

    Cold pilgering is a longitudinal cold-rolling process that reduces the diameter and wall thickness of metal tubes in one process step. Depending on the material, the cold pilger process achieves cross-sectional reductions of more than 90 percent in a single working cycle. Figure 1 shows the principle of the cold pilger process.

    What is Pilgering - Pilger Mill Technologies

    When producing large quantities of tubing, cold drawing is considered to be very slow, compared to the pilgering process. As an example, a cold drawn tube may have to be drawn 3-4 times to equal the same amount of work of a pilger mill. Each time a tube is cold drawn, the tube must be cleaned and annealed (softened) before drawing again.
