Corrosion-Resistant JCOE Steel Pipe for Construction | China Factory Suppliers
Manufacturing Process Excellence
The JCOE manufacturing process involves four precision stages:
| J-Forming | Steel plates are pre-bent into a distinctive "J" shape at both edges |
| C-Forming | The J-shaped plate is further formed into a "C" shape |
| O-Forming | The C-shape is closed into a perfect circular form |
| Expanding | Final calibration ensures perfect roundness and uniform wall thickness |
This controlled forming process minimizes residual stresses and creates pipes with:
- Exceptional concentricity (≤1% ovality)
- Consistent wall thickness (±0.5mm tolerance)
- Superior mechanical properties throughout the pipe body
Technical Specifications & Standards
Key Advantages
