API SPEC 5L PSL1 Longitudinal Submerged Arc Welded Pipes
According to the differences of manufacturing equipment and technology,LSAW is divided into JCOE double side submerged arc welding and UOE double side submerged arc welding.
UOE mill adopts U & O forming, the formed pipes are welded multiple-wire welding inside and outside. In accordance with different requirements of the customers, the welded pipe can be expanded either by mechanical or hydrostatic expander to improve dimensional accuracy, and eliminate residual stress.
UOE production line with high production efficiency,stable good quality,Production and test equipment adopt diversified configuration,To maximize the meet customers’ different requirements.
LSAW steel pipe use steel plate as raw materials and doing Longitudinal Submerged-Arc Welded equipment(the name from the straight weld line). In accordance with the different use for oil transmassion.
At the side of the production process, straight seam welded production process is simple, the production efficiency is high, the cost is low, and it develops rapidly. Compare with spiral steel pipe,the weld seam length of LSAW is more shorter, and the production rate is high.
