LSAW Pipe

LSAW (Longitudinal Submerged Arc Welded) pipe is made by rolling steel plate into pipe blank and adopting double-sided submerged arc welding technology. It features large diameter, heavy wall thickness, high dimensional accuracy, good roundness and strong pressure resistance, widely used in long-distance oil & gas transmission, offshore pipelines, petrochemical projects, bridge piling, high-pressure fluid transmission and large-diameter structural engineering.

It is especially suitable for Middle East large-scale energy projects with high requirements for safety and stability.
