Product classification
According to weld shape classification: Can be divided into straight seam welded pipe and spiral welded pipe
ERW: simple production process, high production efficiency, low cost, rapid development.
Spiral welded pipe: intensity is generally better than straight seam welded pipe is high, can use a narrow diameter of billet production larger pipe can also differ with the same width of the billet production diameter pipe. But with the same length of straight pipe, weld length of 30~100%, and the production rate is low. Therefore, most of the small caliber pipe welded, large diameter welded pipe mostly using spiral welding.
