Spiral characteristics: Longitudinal production process is simple, high production efficiency, low cost, rapid development. Spiral Welded Longitudinal generally higher than, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight seam pipe, weld length of 30 to 100%, and lower production rate. Therefore, smaller diameter pipe is mostly a straight seam welding, large diameter spiral welded pipe for the most part.
