Longitudinal Seam Submerged Arc Welding Pipe

Product description

Longitudinal Seam Submerged Arc Welding Pipe has two types of products. One is  the UOE SAWL pipes, and another is the JCOE SAWL pipes(press bending).The UOE mill features the most advanced technology and process, achieves high production efficiency, stable product quality and is equipped with complete inspection equipment. UOE mill adopts U & O forming, the formed pipes are welded inside through five internal welding stations with three wires, and welded outside through four external welding stations with three wires. 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. As for the JCOE SAWL pipes, this is large diameter longitudinal submerged arc welded (SAWL) pipe production line in China. The mill adopts progressive bending process, featuring evenly distributed forming stress, high uniformity of dimension, infinite sizes variation&wide product range, and high flexibility, etc.
