Special-shaped steel pipe

Special-shaped seamless steel tubes are the general term for seamless steel tubes with cross-sectional shapes other than round tubes. According to the different cross-sectional shape and size of the steel pipe, it can be divided into equal-wall thickness special-shaped seamless steel pipe, unequal-wall thickness special-shaped seamless steel pipe, and variable-diameter special-shaped seamless steel pipe.

Special-shaped seamless steel tubes are widely used in various structural parts, tools and mechanical parts. Compared with round tubes, shaped tubes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.
