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
