Saw Spiral Welded Pipe supplies
Steel coils are extruded at room temperature to make spiral steel pipe, which is then welded using the double wire and double-faced submerged-arc welding technique. Spiral steel pipe, sometimes called spiral or helix spiral steel pipe, is a tube made up of welded joints produced from a low-carbon steel or low-alloy structural steel strip rolled at a specific helix angle (called molding angle).
