STRIP EDGE LAMINATION INSPECTION BY ULTRASONIC METHOD
The Edge test can take place just before the welding during the pipe manufacturing process The control is done under the coil strip on both sides.The
system is used to check lamination..
Pipe manufacturing range : Any Coil width range Thickness range : 5 to 25 mm
Meats specifications API 5L 2000 ISO
3183-3 ARAMCO ..........
The system includes
2 UT probes ( single element)
Multi-channel UT system Fully programmable settings
Marking on tube : - Lamination detection - Loss of coupling Mechanical head and probe holder Data capture
- First printout: produce scanning information for each probe. - Second printout:summary
and full report, traceability of each defect or loss of coupling detected for a complete coil. Storing on CD-Rom Network link
Single crystal probe: near surface resolution better 25 % of the thickness. 25% minimum of the surface coil tested. Lamination control detects a 6.3 mm flat bottom hole at 1/2 plate
thickness. Coupling stability control at each shot
