IRIS Ultima (Internal Rotary Inspection Sytem) is an ultrasonic
technique that gathers thickness data by means of a rapidly rotating pulse-echo
element as it is drawn through a water-filled tube or pipe. It's design is
for the examination of normally inaccessible boiler generating
sections, heat exchangers, air coolers or other small diameter pipe or tubing
that can be accessed from at least one end and be filled or flooded with water.
The average tube size examined ranges from 1.5" to 3" ID, but examinations can be
performed on tubes as small as 3/8" ID and up to 12" with special probes and
The system provides 100% coverage of scanned areas and presents real-time B-scan
presentation of the subject. Saved data can also be presented in colorized
C-scan images as well as numerical format for wall thickness values. This
combination of data presentation enables the technician to determine
both the location, (ID/OD, distance from end of tube) and type (wear, pitting,
general corrosion) of anomaly detected.
The IRIS Ultima system provides for rapid inspection of large volumes of tubes
providing the client with the information needed for operating
and/or maintenance decisions to be made.
