Hollow Section Steel Pipe
What is Hollow Section Steel Pipe?
The hollow section steel pipe is the general name of the steel pipe with other section shapes except the circular pipe. It includes non-circular cross-section profile, equilateral wall thickness, variable wall thickness, variable diameter and variable wall thickness along the length direction, symmetrical and asymmetric section, etc. such as square, rectangular, conical, trapezoidal, spiral, etc. The special-shaped steel pipe can 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. Cold drawing, welding, extrusion and hot rolling are the methods of producing special-shaped tubes. Compared with the circular tube, the special-shaped tube generally has larger moment of inertia and section modulus, and has greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.
