Welded Seam Steel Pipes LSAW
Longitudinal Submerged-Arc Welded Steel Pipe
LSAW (Longitudinal Submerged Arc Welded) pipes or welded seam steel pipes are high-strength welded pipes used in oil and gas, construction, and various industries requiring high-pressure resistance and long-distance transport. Manufactured through submerged arc welding (SAW), it ensures high dimensional accuracy, corrosion resistance, and exceptional structural integrity.
The LSAW manufacturing process involves preparing steel plates (steel sheets), bending, seam welding, and heat treatment, resulting in a strong and precise weld seam.
