Lubrication of tube in cold pilgering
Cold pilgering is a popular cold working process for metallic tubes. Stinnertz (1988) reported that it is widely applied to the manufacture of seamless tubes, including tubes made of steels and copper, titanium, and zirconium alloys. A large cross-sectional reduction of more than 70% is possible in cold pilgering, comparable to that in cold drawing.
