Internal Rotary Inspection System(IRIS)

Internal Rotating Inspection System (IRIS) is a technique using Conventional Ultrasound. An IRIS probe is made of a transducer that generates ultrasounds in the axial direction of the tube towards a 45° mirror. The tube is flooded in water to ensure the necessary coupling for ultrasounds to travel into the parts internal surface (ID) and to penetrate up to the tube’s outer surface (OD). The thickness can be automatically measured. Part of the water supply is used to rotate a turbine which revolves the mirror to ensure a complete 360° coverage throughout the entire length of the tube.


  • Versatile solution providing precise thickness measurements;

  • Effective on various materials and thicknesses;

  • Can be complementary to other techniques;

  • Data visualization can be customized.
