Product Descripton
Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warm extruded and welded byautomatic double wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel to thewelding pipe unit, and the strip steel is rolled by multiple rols. The strip steel is aradually rolled up to form a circular tubeblank with an open gap. Adjust the reduction of the extrusion roll to control the weld gap at i3mm, and make both ends ofthe weld crater flush.
