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.

 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
