Production Process

The manufacturing process of our large-diameter pipes involves:

• Precision Plate Bending: Movable, rotating rolls align and pre-bend steel plates to minimize flat-end lengths.

• Pipe Formation: The plate is clamped and bent into a cylindrical structure, with the option to create conical shapes using advanced roll positioning.

• Multiple Rolling Passes: Ensuring uniform diameter consistency and strength.

• Edge Handling & Tack Welding: Plates are precisely positioned and tack welded before final welding.

• Longitudinal & Circumference Welding: Utilizing SAW welding for strong, seamless joints.

• Ultrasonic Testing: Ensuring structural integrity of welded sections.

• Rigorous Quality Inspections: Every pipe undergoes extensive testing to meet industry standards.

• Coating Inspection: Dry film thickness testing ensures proper paint coating adherence.
