Industry-wide, about 64% of the copper in plumbing tube is derived from recycled scrap, although the percentage varies from zero to 100% among different tube mills. The type of high-quality scrap the mills buy to make tube costs around 90% of the value of newly refined cathode, but its use can be justified because very little refining is needed to return the metal to the purity required for plumbing tube.
Introducing cold pilger mill technologyJul 11, 2006 · The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.
