Cold Drawn Precision Special-Shaped Pipe Application: Cold drawn precision special-shaped pipe is used for mechanical structure, hydraulic equipment with high dimensional precision and good surface finish. Special-shaped seamless steel pipe is widely used in various structural parts, tools and mechanical parts. Compared with the circular tube, the special-shaped tube has a large moment of inertia and section modulus, and has a large bending and torsion resistance capability, which can greatly reduce the structure weight and save steel.
