Straight seam submerged arc welded steel pipe used for the submerged arc welding process technology, the use of filler welding, submerged arc flux particle protection. Production diameter can reach 1500mm, LSAW straight seam submerged arc welding steel pipe is the abbreviation, submerged arc welding straight seam steel pipe production technology has JCOE molding technology, roll-formed SAW technology. When possible to use two large diameter steel plate rolling, it will form a double weld phenomenon.

Can perform standard GB / T3091-2008 low pressure fluid pipe production standard, GB / T9711.1-2 -1997 oil and gas pipe production and use of standards, but also can perform American API 5L line pipe performance standards. Production Material: Q195A-Q345E; 245R; Q345QA-D; L245-L485; X42-X70. Confined main parameters 2ST / T, S is the yield strength, T is the wall thickness. SAW has now become, a double wire submerged arc welding, as well as multi-wire submerged arc welding, to further improve efficiency. Wide range of products for steel, piling, fluid transport, long-distance pipelines and other places.
