SSG's SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. There are 12 sets of modernized production line of SSAW pipe. The annual yield of SSAW pipe with outside diameter 219mm-3620mm, wall thickness 5-25.4mm and steel grade B-X80 is 1,000,000 tons. its two steel pipe production lines, one for spiral submerged arc welded (SAW) steel pipe and one for longitudinal submerged arc welded (SAW) steel pipe, are respectively comprised of two sets of main machines and 1 set of sizing equipment. The annual output comes to 120,000 ton for spiral SAW pipe and 200,000 ton for longitudinal SAW pipe.
