The cross-sectional shape of stainless steel pipes

Stainless steel pipes can be divided into round pipes and irregular pipes according to their cross-sectional shape. Irregular pipes include rectangular pipes, diamond pipes, elliptical pipes, hexagonal pipes, octagonal pipes, and various asymmetric pipes with different cross-sections. Irregular 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, as well as greater bending and torsion resistance, which can greatly reduce structural weight and save steel.
Stainless steel pipes can be divided into equal section pipes and variable section pipes according to their longitudinal shape. Variable cross-section pipes include conical pipes, stepped pipes, and periodic cross-section pipes.
