Spiral submerged arc welded (SSAW) pipes are made from HR coil, where the coil is welded spirally to give a shape of pipe with the capacity to produce 270,000 tonnes of HSAW pipes. It manufactures high quality HSAW pipes conforming to international quality standards. One of the unique features of the two-mirror image HSAW mill is that it can manufacture pipes of same size or two different sizes simultaneously at a very high speed, thereby drastically reducing the delivery time.
