Spiral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding, and welding them into a spiral.
The SSAW pipe is widely used in long distance pipeline project for transmission of oil, natural gas, water as well as coal gas, and also is used in all kinds of engineering, such as chemical industry, electric power, irrigation, construction and piling etc.
Advantages of ssaw steel pipe
(1) The use of steel strips of the same width enables the production of steel pipes of different diameters, in particular the production of large-diameter steel pipes with narrow strip steel.
(2) Under the same pressure conditions, the spiral welds are subjected to a smaller stress than the straight seams, which is 75% to 90% of the straight seam welded pipes, and can therefore withstand greater pressures. Compared with the straight welded pipe with the same outer diameter, under the same pressure, the wall thickness can be reduced by 10% to 25%.
(3) Accurate size, general diameter tolerance is not more than 0.12%, deflection is less than 1/2000, ellipticity is less than 1%, and sizing and straightening processes are generally omitted.
