Technical Performance
The smallest defect, (2 mm diameter x 5 mm deep)
was consistently detected using a 2 mm x 2 mm
scanning resolution on a 35 mm thick plate when using
a 5 MHz transducer with a 50 mm focal length.

The 3D reporting feature ensures hydrogen
blistering and similar type defects can be readily
identified rather than just assumed as is the case
with just 2D C-scan imaging.
Typical applications of the RMS
Corrosion mapping
pp g of:
Above and below ground storage tank floors,
shells and roofs
Pressure vessels including identification of
hydrogen blistering
Process pipe work
Offshore loading /unloading jetty lines once the unit
has been applied by rope access crew
Ships hulls and similar marine vessels
Fracture detection in pressure vessels including
de-lamination checks
USER BENEFITS
* An RMS inspection of a tank shell or roof provides a detailed C scan
report and improved coverage of the area targeted for inspection.
inspection
* Eliminating the need to use scaffolding or rope access to perform manual
UT thickness gauging inspection
* Maximise the ability to detect corrosion by taking 600 mm wide scan
from bottom to top
* Permanent hard and soft copy record of the results which can be
retrieved at any future date.
* Rapid

* Computer generated report in lieu of totally manual reports.
* Reduced safety risks by minimising the use of scaffolding, rope access
