Hexago管是一个一般术语部分钢铁pipes with cross-sectional shapes other than round pipes. There are welded special-shaped pipes and seamless special-shaped pipes. Because of the material, the stainless steel special-shaped tube is generally made of 304 or more materials, and the hardness of 200 and 201 materials is strong and the molding difficulty is increased.

Hexagonal tubes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, stainless steel 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.

Hexagonal pipes are generally distinguished according to their cross-section and overall shape. They can generally be divided into: oval shaped steel pipes, triangular shaped steel pipes, hexagonal shaped steel pipes, diamond shaped steel pipes, stainless steel patterned pipes, stainless steel U-shaped steel pipes, D-shaped pipes, Stainless steel elbows, S-shaped pipe elbows, octagonal shaped steel pipes, semi-circular shaped steel rounds, unequal hexagonal shaped steel pipes, five-petal plum shaped shaped steel pipes, double convex shaped steel pipes, double concave shaped steel Water elbow, melon seed shaped special-shaped steel pipe, conical shaped special-shaped steel pipe, corrugated special-shaped steel pipe, etc.
