SSAW steel pipe is a steel strip coil plate of raw materials,extrusion at normal temperature,with automatic double wire welding double-sided submerged arc welding technology with spiral seam pipe.
a.Molding process, the steel plate uniform deformation, residual stress is small, the surface does not produce scratches.Processing of SSAW steel pipe on the scope of the size of diameter and wall thickness is more flexibility,especially in the production of high grade thick wall tube, especially small and medium caliber thick wall tube has incomparable advantage over other processes,can meet more needs of users in the spiral steel pipe specifications.
