Production:
LSAW steel pipe is parallel to the pole longitudinal steel pipe.Usually divided into metric welded steel pipe, welded thin-wall tube, transformer cooling pipe and so on.Straight seam welded pipe production technology is simple, high production efficiency, low cost, rapid development.The strength of the spiral 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 *0 ~ **0%, and the production speed is low.
