Spiral welded steel circular hollow section(SSAW), commonly referred to as spiral steel pipe, is a spiral seam steel pipe welded by automatic double wire double-sided submerged arc welding process with strip steel coils as raw materials, often warm extruded.


circular hollow section(SSAW) sends the strip steel to the welding pipe unit, and the strip steel is rolled by multiple rolls. The strip steel is gradually rolled up to form a circular tube blank with an open gap. Adjust the reduction of the extrusion roll to control the weld gap at 1~3mm, and make both ends of the weld crater flush.
