Product Description

Introduce

Specially shaped seamless steel pipes are widely used in various structural components, tools, and mechanical components. Compared with circular pipes, special-shaped pipes generally have larger moments of inertia and cross-sectional modulus, and have greater bending and torsion resistance, which can greatly reduce structural weight and save steel.
Special shaped pipes are generally distinguished based on their cross-sectional area, and can be divided into seamless steel pipe special shaped pipes, aluminum alloy special shaped pipes, and plastic special shaped pipes according to their materials. Below, we will mainly introduce the special shaped steel pipe.
Steel pipe shaped pipes can be divided into elliptical shaped steel pipes, triangular shaped steel pipes, hexagonal shaped steel pipes, diamond shaped steel pipes, octagonal shaped steel pipes, semi-circular shaped steel pipes, unequal hexagonal shaped steel pipes, five petal plum blossom shaped steel pipes, double convex shaped steel pipes, double concave shaped steel pipes, melon shaped steel pipes, conical shaped steel pipes, and corrugated shaped steel pipes.
