Rectangular Steel Pipe
The specific meaning of rectangular steel pipe:
Rectangular steel pipe is a kind of special-shaped pipe, so special-shaped seamless steel pipe is widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce structural weight and save steel.
Special-shaped pipes are generally distinguished according to the broken section, and can be divided into seamless steel pipe special-shaped pipes, aluminum alloy special-shaped pipes, and plastic special-shaped pipes according to the material. The following mainly introduces the special-shaped steel pipe.
Special-shaped steel pipes can be divided into oval shaped steel pipes, triangular shaped steel pipes, hexagonal shaped steel pipes, diamond shaped steel pipes, octagonal shaped steel pipes, semi-circular shaped steel rounds, unequal-sided hexagonal shaped steel pipes, five-petal plum shaped shaped steel pipes, Double convex shaped steel pipe, double concave shaped steel pipe, melon seed shaped steel pipe, conical shaped steel pipe, corrugated shaped steel pipe.
