What is IRIS - Internal Rotary Inspection System?
The IRIS “Internal Rotary Inspection System” is ideally suited to the inspection of carbon steel tubing although the technique can successfully be applied to all types of tubing materials.
Method of Inspection | Applications
IRIS uses a transducer to generate an ultrasonic pulse parallel to the axis of the tube under test relying on a rotating mirror that directs the ultrasonic wave into the tube wall. The mirror is driven by a small turbine powered by the pressure of water pumped into the tube.
Part of the ultrasonic wave is reflected by the inner-diameter (ID) wall, while the rest is reflected by the outer-diameter (OD) wall of the tube. Because the ultrasonic velocity of the tube’s material is known, it is possible to assess the thickness of the wall by calculating the difference in times of flight between the two diameters. As the probe is pulled, the spinning motion of the mirror results in a helical scan path.
