LSAW Longitudinally Submerged Arc Welded Steel pipes in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.The coherence of cutter head and plate clamping system guarantees the invariable parameters during the entire milling process; accordingly it ensures the milling quality and lays a good foundation for the success of subsequent welding.
Usage: Used for low pressure liquid delivery, such as water, gas, and oil.
