The cold pilgering process involves several stages. Initially, the metal tube is fed into the mill, where it is drawn through a series of dies and rollers. This process strains the material, which increases its strength and hardness due to the cold working effect. The pilgering process not only reduces the diameter of the tube but also improves its surface finish and mechanical properties. As a result, products manufactured using a cold pilger mill are often sought after for applications in industries such as oil and gas, aerospace, and chemical processing.
