IRIS - Internal Rotary Inspection
System - is an ultrasonic system for inspection of heat exchangers and
boilers. It employs the conventional pulse-echo technique for measuring
the wall thickness,
but uses novel methods for displaying the measurements.
All measurements made during a complete scan around the circumference
of the tube, are displayed on the computer screen, producing real time
rectangular or circular pictures. Alternatively, it is also possible to
obtain the picture in the C-Scan and D-Scan systems.
False measurements can be easily recognized and compensated for by extrapolation
of those measurements. This methodology allows wall thickness measurements
of less than 0.5 mm under special conditions.

Advantages of IRIS
inspections:
• Detects corrosion, abrasion,
pitting and holes
• Measures pitting as
small as 1.5 mm diameter
• Measures when remaining
wall thickness is less
than 0.5 mm
• Inspects tubes from
9 to 76 mm internal diameter
with basic equipment, reaching up to 355 mm
with a special centralizing device
• Avoids downtime losses
due to tube failures
• Negotiates bends in
boiler tubes |

Any of the four alternatives provided by the IRIS system displays, shows
precisely, the actual conditions of the tube.
The equipment shows
diferent images of the same external tube corrosion:
rectangular, circular, C-Scan and D-Scan.

• Allows
on screen wall thickness measurement
• Provides data to evaluate
tubes remaining lifetime
• Reports tubes actual
condition and thickness
• Inspects both ferrous
& nonferrous materials
• Indicates and measures
abrasion generated by
baffles
• Detects problems in
or at tube sheet area
• Shows easy to interpret
results
• Provides results that
can be stored in disks or CDs
