Shaped Copper Tube

The development of special-shaped copper tubes is mainly the development of product varieties, including cross-sectional shape, material and performance. Extrusion method, diagonal die rolling method and cold drawing method are effective methods for producing special-shaped copper pipes, which are suitable for producing special-shaped pipes of various cross-sections and materials. In order to be able to produce a wide variety of special-shaped copper tubes, it is necessary to have a variety of production methods. In the 1990s, my country developed dozens of production methods such as roll drawing, extrusion, hydraulic pressure, spinning, spinning, continuous rolling, rotary forging and dieless drawing based on the original cold drawing. Continuously improve and create new equipment and processes.
