TUYAU EN ACIER SSAW
SSAW steel pipe is also known as the Spiral Submerged- Arc Welded Steel Pipe that is a type of spirally welded steel pipe produced by using the double-sided submerged arc welding method. Spiral welded pipes are formed using narrower plates or hot rolled coils, which lowers their production costs significantly. The spiral welding process permits the production of large-diameter pipes suitable for transporting large volumes of oil and gas.
