Power Generation
We provide nondestructive inspection products and solutions for key power generation applications,
including those for fossil, nuclear, renewable energy markets, transmission and distribution. Our
reliable, advanced technology inspection solutions and support services enable power generation
customers to help maximize efficiency, minimize downtime and enhance productivity with unyielding
integrity.
Feed water heaters, condensers and heat exchangers
Proper operation of these crucial components is
essential for ecient operation of a power plant. Each
machine is inspected internally and externally for
tness for service. Our menu-directed remote visual
inspection and eddy current systems can detect
defects and cracks that cause leaks.
Primary and secondary piping
To prevent leakage and failures, piping is regularly
inspected for corrosion, weld defects and gas
accumulation using ultrasonics, remote visual
inspection and direct radiography systems. These same
technologies are also used to inspect pipes, welds and
vessel components to help ensure integrity.
Reactor vessel
High-pressure boilers and vessels are kept operating safely using
remote visual inspection. Regular inspection for cracks and defects
help ensure safe operation and help prevent loss of structural integrity
of the vessel.
Combined
Cycle
Hydro
Nuclear
Nuclear submarines
To help ensure maximum safety of a
submarine crew, numerous nondestructive
tests are carried out to verify quality of
the vessel girth welds, steam generator
system, primary and secondary piping
and reactor vessels. The submarine
environment demands use of all
nondestructive technologies to help
ensure safety.
Nuclear fuel and fuel rods
Ultrasonics, eddy current and radiography are commonly used in
the manufacturing environment to test rods for ovality to ensure the
rods t into a fuel cluster. A fuel assembly that does not t precisely
as designed can cause long and unacceptable delays in a plant
maintenance outage.
Turbines and generators
Using our remote visual inspection, eddy
current and ultrasonic systems, blades and
dovetails found in rotating machines, such
as turbines and generators, are inspected
for cracks and defects to minimize
downtime and possible injury.
Wind generation
Condition-based inspection of the gearbox in the
nacelle decreases the likelihood of catastrophic failure
and enables scheduling of repairs and preventative
maintenance. Our easy-to-use remote visual inspection
systems require no special training, while producing
more uniform inspection results.
Image and data sharing
Rhythm software ties all inspected components of the plant into one data le and
helps plant operators plan maintenance rather than react to forced outages. DICONDE
compliant, this software platform is compatible with our digital radiography, phased
array ultrasound, remote visual inspection and eddy current technologies. Rhythm
encompasses the image management tools that help ensure thorough inspection results
and rapid data sharing.

Transmission and distribution
Remote visual inspection of switches helps
ensure compliant and safe operation of
the substation. Digital Radiography allows
for condition-based maintenance of
gas-insulated switches.

Manufacturing
Manufacturing power plant components
The very low tolerance for manufacturing defects
or foreign matter inclusions in large forgings, such
as turbine shafts or in controlling piping and vessel
materials, is mitigated by using nondestructive testing
systems in the manufacturing facility. Our radiography,
lm or digital solutions, coupled with ultrasonics, detects
volumetric defects. Our eddy current systems are used
for near surface defect detection.
Blade manufacturing for wind energy
Throughout the steps of the blade
manufacturing process, ultrasonic
technology is used to test composite
material for delaminations and defective
layering to ensure quality. The bonding
of portions of the blade to one another
and support structures is also monitored
using ultrasonics.
