Beyond the Specifications
Key Benefits That Deliver Tangible Project Value
1 Unrivaled Durability & Structural Integrity
The JCOE manufacturing methodology is central to achieving a product that stands the test of time and stress.
- Optimal Stress Distribution: Unlike some methods, the step-by-step JCOE process avoids material over-stretching, preserving the steel's inherent metallurgical properties and resulting in a more uniform, stress-resilient pipe body.
- Perfect for Thick-Wall, Large-Diameter Applications: This process is exceptionally capable of producing pipes with large diameters and significant wall thicknesses, which are essential for high-pressure transmission lines and major structural piling.
- Superior Weld Seam Quality: The precise "O" shape before welding ensures a consistent seam gap, allowing our automated Submerged Arc Welding (SAW) to produce a homogeneous, high-strength weld that is meticulously inspected via UT and RT.
- Long-Term Performance Security: The mandatory normalizing heat treatment post-welding is a critical differentiator. It eliminates residual stresses, refines the grain structure, and dramatically improves the pipe's resistance to fatigue and brittle fracture, ensuring safety over decades of operation.
