Spiral steel pipe is a spiral seam steel pipe which is made of steel coiled coil as raw material, which is often heated and extruded, and welded by automatic double wire double-sided submerged arc welding process. The advanced double-sided submerged arc welding process can achieve welding at the best position, and it is not easy to have defects such as wrong side, welding deviation and incomplete penetration, and it is easy to control the welding quality. Spiral steel pipe is mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction owing to its sturdy construction with high strength and wear resistance.
