Spiral welded pipeproduction uses hot rolled coil.
The alloy content of the coil is often lower than similar grades of steel plate, improving the weldability of thespiral welded pipe。由于滚动方向spiral welded pipe线圈不垂直于管道轴方向，裂缝电阻spiral welded pipe材料。
由于螺旋管的独特性能，何时spiral welded pipeblasting occurred, the weld suffered stress and co-stress is relatively small, blasting the mouth is generally not the origin of the spiral weld, so the higher security. Spiral weld near the defect with parallel spiral weld force is smaller, so the risk of expansion is not.
钢管经受内部压力，通常在墙上的两个主要施用力，径向应力ΔY和轴应力Δx。焊接结果应力Δ=ΔY（L /4Sin2α+COS2α）1/2，即α是螺旋焊接管的螺旋角。螺旋焊管的螺旋角通常为50-75度，因此螺旋焊接大致应力。在相同的直径的压力下在相同的工作spiral welded pipe壁厚可以减少很多，螺旋管道可以制成小口径。
规范，标准和识别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.
