Spiral submerged arc welded pipe (SSAW) is a strip steel pipe with a forming angle (adjustable) between the forward direction and the center line of the formed pipe. It is welded while forming, and the weld becomes a spiral. The advantage is that strip steel of the same specifications can be produced Steel pipes of various diameters have a wider range of raw materials, and the welds can avoid the main stress and have better stress conditions. The disadvantage is that the geometric size is poor, the weld length is longer than that of straight seam pipes, and cracks, pores, and Welding defects such as slag inclusions and welding deviations cause the welding stress to be in a tensile stress state.After improving this process abroad, the raw material is changed to the steel plate, so that forming and welding are separated. After pre-welding and hardening, and cold expansion after welding, the welding quality is close to that of UOE pipes.
