  • 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.
