Tube Inspection – Internal Inspection Rotary System IRIS

IRIS testing uses an ultrasonic beam scanned around the tube ID by a water driven turbine probe assembly as illustrated below. This is inserted in each tube and then withdrawn.

The ultrasonic system used by IRISNDT both collects and stores ultrasonic signals as the assembly is withdrawn. The ultrasonic data is displayed in real time but is also available for post test analysis and reporting. The software generally displays the data in colour coded topside and end views for evaluation of any indications of thickness changes.

IRIS Inspection Applications

IRIS is widely used to examine heat exchangers, boilers, and fin fan cooler tubes. It can be applied for ferromagnetic and non-ferromagnetic materials. This technique is very good for detecting and sizing corrosion, erosion, and baffle wear.

Up to Date Instrumentation

IRISNDT Inspection uses the latest technology to record data from the entire length of the tubes. Stored data is displayed using C-scan, B-scan and D-scan images for better and more accurate results. The stored data can also be reviewed off-line or replayed at a later date for comparison with subsequent inspection data.

Tube Cleanliness

Thorough cleaning is essential for good data quality and a reliable inspection. Deposits and scale in the tubes will block the ultrasonic beam and prevent examination of the tube wall. Any defects in ‘dirty’ areas will be missed.
