SAW SPIRAL PIPE-ON LINE BODY LAMINATION INSPECTION BY ULTRASONIC METHOD

The body lamination test can take place just after the welding during the pipe manufacturing process and can operate at high scanning speed.

   Pipe manufacturing range :
    -Pipe diameter range :500 mm to 3000 mm
    -Wall thickness range:5 mm to 25 mm
    -Coil width range : 900 mm to 2000 mm

Meets Specifications

API 5L 2000
ISO 3183-3
ARAMCO

   The system includes

  UT probes ( 4 to 8)
  Multi-channel UT system (2000
      meas/S.
  Fully programmable settings
      Marking on tube :
            -  Lamination detection
            -  Loss of coupling
  Mechanical head oscillator and
      probe holder (600 mm/S)
  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.

  Twin crystal probes: focal length 
      at 50 % of the wall 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.
