Characteristics of ssaw steel pipe: straight seam welded pipe production technology is simple, high production efficiency, low cost, rapid development.The strength of the ssawl welded pipe is generally higher than straight seam welded pipe, use a narrow billet production of larger diameter welded pipe, you can also use the same width of billet in the production of different pipe diameter welded pipe.But compared with the same length of straight seam pipe, weld length by 30 ~ 100%, and the production speed is low.As a result, a small diameter welded pipe are mostly with straight seam welding, large diameter welded pipe for the most part adopts spiral welded
