LSAW Pipe Description
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. The production equipment can be produced quickly, easy to replace, and the product specification range of LSAW pipe is large. The production line can produce welded pipe diameter 406-4500mm, wall thickness 8mm-100mm.
