The Internal Rotary Inspection System (IRIS) is a Non-Destructive Ultrasonic Testing method. This advanced technology is generally used for the measurement of wall thinning and pitting due to corrosion and erosion of small bore pipes.

The IRIS probe produces very accurate and detailed results. The data can be safely used in integrity assessment studies and remaining life-time calculations.

This NDT method is generally used for inspection of heat exchanger and steam generator tubes and pipes in the chemical, petrochemical and (nuclear) energy industries. RIS technology can be used to detect and quantify pitting and damaged areas as well as a general reduction in wall thickness, so that the condition of the entire pipe cluster can be charted.
