LSAW Steel Pipe

Kinukuha ng LSAW Pipe ang steel plate bilang hilaw na materyal, hinuhubog ito ng molding machine, pagkatapos ay gawin ang double-sided submerged arc welding. Sa pamamagitan ng prosesong ito ang LSAW steel pipe ay makakakuha ng mahusay na ductility, weld toughness, uniformity, plasticity at mahusay na sealing.
