CORROSION PREVENTION AND CONTROL WORLDWIDE MATERIALS PERFORMANCE
Inspection and monitoring technology available today is
making it much more efficient to spot degradation and
corrosion. In recent years, using unmanned aerial vehicles
(UAVs), or drones, for surveillance operations to help
detect signs of corrosion has surged in popularity across
many industries, led by oil and gas and others prone to
corrosive deterioration. This technology is a game-changer
for industry, in that various inspection and detection
instruments can now be attached to a drone and flown
into places that were previously very difficult or dangerous
to access. Several projects where companies are using
UAVs to inspect for corrosion are discussed in the feature
article that starts on p. 28. Additionally, various nonintrusive
corrosion monitoring techniques—such as ultrasonic
testing, fiber-optic sensors, and electric field mapping—
are reviewed in the technical article on p. 52. This month in
NACE News, see the third article on NACE's Strategic Plan
on p. 58.
