Product Description
Product Overview
Zhengde special-shaped steel pipes are non-round seamless steel pipes available in various cross-sectional shapes. These include equal wall thickness, unequal wall thickness, and variable diameter configurations designed for structural applications.
Applications & Advantages
Special-shaped seamless steel pipes are widely used in structural components, tools, and mechanical parts. Compared to round pipes, they offer larger moment of inertia and section modulus, providing superior bending and torsion resistance while reducing structural weight and saving steel.
Available Shapes
- Oval special-shaped steel pipes
- Triangular special-shaped steel pipes
- Hexagonal special-shaped steel pipes
- Rhombus special-shaped steel pipes
- Octagonal special-shaped steel pipes
- Semi-circular special-shaped steel pipes
- Unequal hexagonal special-shaped steel pipes
- Five-petal plum blossom shaped pipes
- Double convex and double concave shapes
