LSAW (Longitudinal Submerged Arc Welded) steel pipe is a type of large-diameter Welded Steel Pipe that is manufactured using the submerged arc welding process.
LSAW steel pipes are commonly used for long-distance pipelines, such as oil and gas transmission lines, water pipelines, and infrastructure projects.
The process of LSAW Steel Pipe:
Plate feeding → Edge Milling and Beveling → Board Probe → Edge Crimping →molding→Slag→Track Pre-Welding → Tab Welding → Inside Welding → Slag → Outside Welding → Tab Removal → Ultrasonic Inspection → X-ray Inspection → Mechanical Expansion → Flame Flat → Hydro-static Testing → Ultrasonic Inspection for pipe end and welding seam → Weld and Pipe End X-ray Inspection → Tube end weld grinding → End Facing and Beveling → Weighing and measuring → Spray paint Marking → Final Inspection → Storage → Storage and Shipment
