Submerged arc welded pipe: steel strip coil is as raw material, often warm extrusion molding, two-wire double-sided submerged arc welding process automatically welded spiral seam steel pipe.

Submerged arc welded steel submerged arc welded pipe Features: welded pipe production process is simple, high efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than the Longitudinal, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different diameters of pipe. However, compared with the same length of straight seam pipe, the weld length increased by 30 to 100%, and lower production rate. Therefore, smaller diameter pipe mostly straight seam welded pipe of large diameter are mostly spiral welded.
