What is the JCOE Process?

JCOE is a sophisticated cold-forming technique. Steel plates are precisely shaped through a series of steps:

· J (Joggle-End Pressing): The plate ends are pre-formed to ensure a perfect fit for welding.

· C (Crimping): The long edges of the plate are curved to the required radius.

· O (O-forming): The plate is gradually pressed into a circular "O" shape through multiple steps.

· E (Expanding): The welded pipe is mechanically expanded. This crucial step optimizes dimensional accuracy, relieves internal stresses, and improves overall pipe strength and roundness.

Key Advantages of Our JCOE LSAW Pipes:

· Superior Mechanical Properties: The controlled forming and expanding process enhances yield strength and tolerances.

· Excellent Dimensional Accuracy: Ideal for projects requiring precise fit and alignment.

· Wide Size Range: Capable of producing larger diameters and thicker walls compared to other methods.

· High-Quality Welds: Submerged Arc Welding (SAW) ensures a robust, consistent, and reliable weld seam.
