Spiral steel pipe(ssaw) is a steel pipe with spiral seam, which is made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. It is mainly used in pipeline transportation of oil, natural gas, bridges, docks, roads, buildings and other projects.
Spiral steel pipe generally adopts advanced double-sided submerged arc welding process, which can realize welding in the best position, and is not prone to defects such as misalignment, welding deviation and incomplete penetration, and it is easy to control the welding quality. The raw materials are strip coil, welding wire and flux. It has to undergo a rigorous physical and chemical inspection before it is put into use.
