LSAW Pipe Longitudinal Submerged Arc Welding

Product origin China
Delivery time 15-25 Working Days
Supply capacity Factory Direct Supply

The longitudinal submerged arc welded pipe is made of steel plate as raw material, which is formed by a forming machine, and then double-sided submerged arc welding is carried out. Through this process, the LSAW pipe will have excellent ductility, toughness, uniformity, plasticity and good sealing performance.
