Description

LSAW Steel Pipe (Longitudinal Submerged Arc Welded Steel Pipe) is a type of welded steel pipe produced using the submerged arc welding process with a longitudinal (straight) seam. It is widely used for large-diameter and thick-walled applications where high strength and reliability are required.
LSAW pipes are typically manufactured from high-quality carbon steel or low-alloy steel (such as Q235, Q345, or API 5L grades) through processes like plate forming, welding, and expansion. This results in excellent dimensional accuracy, strong weld integrity, and superior mechanical performance.
