Spiral steel pipe features: straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank, and it can also produce welded pipe with different pipe diameter with blank of the same width. But compared with the same length of straight seam pipe, the weld length increases by 30~100%, and the production speed is lower. Therefore, small diameter welded pipe mostly adopts straight seam welding, large diameter welded pipe mostly adopts spiral welding.
