Product Description
Product Overview
Zhengde special-shaped steel pipes represent a comprehensive category of seamless steel pipes featuring non-circular cross-sections. These include equal wall thickness, unequal wall thickness, and variable diameter configurations, manufactured from carbon steel grades 1020, Q355, Q195, and Q235.
Applications & Advantages
Special-shaped seamless steel pipes are extensively used in structural components, tools, and mechanical parts. Compared to round pipes, they offer superior moment of inertia, section modulus, and enhanced bending/torsional resistance, enabling significant weight reduction and steel savings in structural applications.
Available Profile 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 profiles
- Melon-shaped, conical, and corrugated pipes
