Product Description
Product Description
Spiral steel pipe is a spiral seam steel pipe made of strip coil plate, extruded at constant temperature and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe will send the strip into the welding pipe set. After being rolled by a multi-channel roll, the strip gradually rolls up to form a circular tube blank with an open gap. The pressure of the extrusion roll is adjusted so that the weld gap is controlled within 1~3mm and the two ends of the welding joint are flush.
