Introduce
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.

Features and Applications
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.
Specially shaped pipes are generally distinguished according to the cross section. According to the material, they can be divided into seamless steel pipe special-shaped pipes, aluminum alloy special-shaped pipes, and plastic special-shaped pipes. The following is mainly about steel pipe specials.
The steel pipe special-shaped pipe can be divided into elliptical special-shaped steel pipe, triangular special-shaped steel pipe, hexagonal special-shaped steel pipe, rhombic special-shaped steel pipe, octagonal special-shaped steel pipe, semicircular special-shaped steel circle, unequal hexagonal special-shaped steel pipe, five-petal plum shaped special-shaped steel pipe, double-convex special-shaped steel pipe, double-concave special-shaped steel pipe, melon shaped special-shaped steel pipe, conical special-shaped steel pipe, corrugated special-shaped steel pipe.
