Submerged Arc Spiral Welded Tube For Gas Lines
Spiral welded pipes are produced continuously and can theoretically produce infinitely long steel pipes. This production process minimizes head and tail cutting losses while increasing metal utilization by 6% to 8%. This will result in cost savings and efficiencies for our customers.
Our spiral welded tubes offer superior operating flexibility compared to traditional straight seam welded pipes. Easy to swap out and adjust varieties, making them ideal for projects that require adaptability and customization. Additionally, the mechanization and automation capabilities of our spiral welded tubes allow them to be easily implemented in a variety of industrial environments.
