DSAW(Double-sided spiral submerged arc welded pipe)characteristics: production process of welded pipe is simple, high efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than dsaw pipe and 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, Weld length increased by 30 to 100%, and lower production rate.

DSAW(Double-sided spiral submerged arc welded pipe) are widely used in natural gas, petroleum, chemicals, electricity, heating, drainage, steam heating, hydropower penstock, thermal power, water and other long-distance pipelines, piling, dredging, bridges, steel and other engineering fields.
