Seamless Carbon Stainless Special Shaped Steel Pipe 0.5-2mm Thickness 4-200mm Diameter
Zhengde Special-shaped steel pipes are seamless steel pipes with non-circular cross-sections, offering superior structural performance compared to standard round pipes. Available in various configurations including equal wall thickness, unequal wall thickness, and variable diameter designs.
Special-shaped seamless steel pipes are widely used in structural components, tools, and mechanical parts. Compared to round pipes, they provide larger moment of inertia and section modulus, offering enhanced bending and torsion resistance while reducing structural weight and saving steel.
