Our Advanced NDT experts provide Internal Rotary Inspection System (IRIS) services. 

IRIS is an ultrasonic method used for the non-destructive testing of pipes and tubes.

Many plant operators in the oil, gas and power generation industries are faced with the challenges of maximising the efficiency and life expectancy of their assets but without sacrificing safety and reliability. Therefore accurate inspection of vital components such as pipes and tubes is crucial to ensuring the integrity of the plant.

​

Internal Rotary Inspection System (IRIS) can detect corrosion, pitting and wall loss and is most commonly used for tube inspection in boilers, heat exchangers, air coolers and feed water heaters. It is particularly versatile as it is suitable for both ferrous and non-ferrous materials, and IRIS can be used on a wide range of tube diameters and wall thicknesses.
