Product Description
Special Shaped Seamless Steel Pipe Overview
Zhengde Special-shaped steel pipes are seamless steel pipes with non-circular cross-sectional shapes. These include equal wall thickness, unequal wall thickness, and variable diameter configurations, offering superior structural performance compared to traditional round pipes.
Applications and Benefits
Special-shaped seamless steel pipes are widely used in structural components, tools, and mechanical parts. They provide greater moment of inertia and section modulus than round pipes, resulting in enhanced bending and torsion resistance while reducing structural weight and steel consumption.
Available Cross-Section 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 steel pipes
- Double convex and double concave special-shaped pipes
- Melon-shaped, conical, and corrugated special-shaped pipes
