SSAW spiral weld line distribution, long welds, especially under dynamic conditions in welding, the weld had a chance to cool down on the left molding point, easy to produce welding hot cracking.
Crack direction and parallel to the weld, and pipe axis into a certain angle, usually between 30-70 °. This angle is just consistent with the angle of shear failure, so the flexural, tensile, compressive and torsional performance is far better than LSAW pipe, and because of welding position limit, and fish ridge saddle weld impact of beautiful. In addition, the construction process, intersecting lines spiral welded seam mother pipe at a node separates the spiral, a greater welding stress, thus greatly impair the safety performance of member, and therefore efforts should be strengthened NDT spiral welded seam, ensure the welding quality, otherwise important occasion not to use spiral submerged arc welded steel pipe.
Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.
Our team is highly trained and experienced in servicing and producing all types of steel supplies.
