INFORMATION
Longitudinal Submerged Arc Welded (LSAW) steel pipes are a type of high-performance steel pipe primarily used in heavy-duty industries like oil and gas transportation. They are produced by bending and welding steel plates, resulting in a pipe with a single longitudinal seam. LSAW pipes are known for their large diameter, thick wall, high-pressure resistance, and strong structural integrity, making them suitable for long-distance pipelines and underwater services. Despite being more labor-intensive and costly than other pipe types, their strength and durability make them an invaluable asset in demanding conditions. O.D. W.T.
