Newsest Hot Sales pipe fitting molds Producers:Ssaw is the abbreviation of spiral submerged arc welding, that is, spiral submerged arc welded pipe. Ssaw Tube is a spiral welded pipe, also known as spiral welded pipe, spiral welded pipe or spiral welded pipe. The narrowband (plate) coil is welded continuously into steel pipe by using double-sided submerged arc welding spiral welding technology.

Widely used in long-distance oil and gas pipeline engineering such as west-to-east gas transmission in China, it is the main pipeline type used in long-distance oil and gas pipeline engineering in China.
Spiral steel pipe is widely used in natural gas, petroleum, chemical industry, electric power, heat, water supply and drainage, steam heating, hydropower station pressure pipe, thermal power, oil feed and other long-distance pipeline and piling, dredging, bridges, steel structure and other engineering fields. Longitudinal welded pipe production process is simple, high production efficiency, low cost, rapid development.
Spiral welded pipe is generally stronger than straight welded pipe. Spiral welded pipes can be produced with narrower blanks. The same width, different diameter of the blank can also be produced spiral welded pipe. However, compared with the same length of straight seam pipe, the standard weld length of spiral welded pipe is increased by 30-100%, and the standard production speed of spiral welded pipe is low. Therefore, the small diameter welded pipe is mostly straight seam welded pipe, large diameter welded pipe is mostly spiral welded pipe.
