Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. It can be made with narrower Strip steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness. The welded pipe should ensure that the hydraulic test, the tensile strength of the weld and the cold bending performance must meet the regulations.
In terms of welding process, the welding method of spiral welded pipe and straight seam Steel Pipe is the same, but the straight seam welded pipe will inevitably have a lot of T-shaped welds, so the probability of welding defects is also greatly increased, and the welding residue at the T-shaped welds The stress is large, and the weld metal is often in a three-dimensional stress state, which increases the possibility of cracks.
Moreover, according to the technical regulations of submerged arc welding, each weld should have an arc starting point and an arc extinguishing point, but each straight seam welded pipe cannot meet this condition when welding a circular seam, so there may be More welding defects.
