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