Spiral Submerged Arc Welded Pipe SSAW
The spiral submerged arc welded pipe is made of hot-rolled steel strip through constant temperature spiral forming and automatic submerged arc welding. The manufacturing process is to roll the steel strip, make the rolling direction at a certain angle to the center direction of the tube, and then form and weld, so the weld is spiral.

Spiral Submerged Arc Welded Pipe SSAW Description

Submerged  arc welding is an important welding method. Its inherent advantages  include stable welding quality, high welding productivity, no arc light  and little smoke, making it an ideal choice  in  the production of important steel structures such as pressure vessels,  pipe section manufacturing, box beam and column manufacturing. The  strength of SSAW spiral welded pipes is generally higher than that of  straight seam welded pipes. Welded pipes with larger diameters can be  produced from narrower billets, and welded pipes with different  diameters can also be produced from billets of the same width.
