It includes non-circular cross-section profile, equal wall thickness, variable wall thickness, variable diameter and wall thickness along the length direction, symmetrical and asymmetric cross-section. Such as square, rectangular, conical, trapezoidal, spiral, etc. The special-shaped steel pipe can better adapt to the particularity of the use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, textile and boiler manufacturing. The methods of producing special-shaped pipes include cold drawing, electric welding, extrusion, hot rolling, etc., and the cold drawing method has been widely used

The production process of special-shaped steel pipes is like a carefully choreographed dance, and each step is full of the fusion of technology and wisdom.
Special-shaped seamless steel pipe is widely used in various structural parts, tools and mechanical parts. Compared with round pipe, special-shaped pipe generally has larger inertia moment and section modulus, and has greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.
