  IRIS is an ultrasonic technique used for the inspection of a
  wide range of materials, including both non-ferromagnetic and
  ferromagnetic tubing.
  • Allows for the detection and sizing of wall loss as a result of corrosion, erosion, tube-to-tube wear, pitting, fretting,
  cracking and baffle cuts.
  • Focused ultrasonic probe and a rotating mirror to produce
  a helical scan.
  • Ultrasound is reflected from the tube ID and OD and the
  time difference is used to calculate the thickness.
  • IRIS is a great backup and verification tool for the other
  tube inspection techniques
  • IRIS data to be presented as a B, C, or D-scan image.
