Longitudinal Submerged-Arc Welded Steel Pipe
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.
