Special-shaped seamless steel pipes

Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have a larger moment of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.
The development of special-shaped pipes is mainly the development of product varieties, including cross-sectional shape, material and performance. Extrusion, diagonal die rolling and cold drawing are effective methods for producing special-shaped pipes. They are suitable for producing special-shaped pipes of various cross-sections and materials. In order to produce a wide variety of special-shaped pipes, a variety of production methods must be available. In the 1990s, based on the original cold drawing, my country developed dozens of production methods such as roll drawing, extrusion, hydraulic pressure, rolling, spinning, continuous rolling, rotary forging and dieless drawing, and in Continuously improve and create new equipment and processes.
