Magnetic NDT Continues to Advance at Eddyfi as It Triples in Size & Expands in
Scope
spection methods have been a key factor in propelling Eddyfi
forward to new technical capabilities and into new markets.
Its pulsed eddy current technology is a good example. Eddyfi
makes specialized eddy current instruments such as
Lyft along with a line of application specific probes by which
the system can be adapted to various structures in the field
needing inspection such as pipelines, storage tanks, ships
and many more. Its innovative PEC Array Probe employs a
six-channel array and slashes the inspection time of singleelement
probes while accommodating a variety of surfaces
and materials.
In the high-stakes world of non-destructive testing where
failure to detect flaws can lead to disastrous consequences in
energy facilities, pipelines and aircraft, Eddyfi Technologies
continues to build its magnetic systems while also growing
aggressively into ultrasonic and other methods. Now a
formidable global player providing both equipment and crews
for testing, in little more than a year the company has tripled in
size through acquisitions and expanding business activities.
A hallmark of the company's capabilities is the ability to detect
corrosion under insulation commonly seen as one of the greatest
challenges facing asset integrity. Its specialized Pulsed
Eddy Current (PEC) system, depicted above, has become a
familiar sight where technicians need to quickly screen insulated
steel for corrosion
Recently, the company broadened significantly via the acquisition
of Dublin, Ireland-based NDT Global, a leading supplier
of ultrasonic inline inspection and integrity (ILI) services. The
move brought both a major play in ultrasonic testing to Eddyfi,
now part of the new parent company Eddyfi/NDT, as well as
a large service operation capable of employing a spectrum of
NDT methods.
It capped a string of acquisitions in recent years that have
broadened the firm into both a manufacturer of a variety of
types of NDT equipment as well as a provider of field services.
In about a year's time, the company has grown from a $100
million operation to $300 million, emerging as a disruptive top
player in the NDT market in just the tenth anniversary year for
the Quebec-based firm.
" We have spent the past 10 years developing, acquiring and
perfecting the most advanced NDT modalities in the world, "
said Martin Theriault, CEO of Eddyfi/NDT. " At every level
of technology, pushing the limits of NDT to new heights has
allowed us to solve critical problems and deliver superior,
information-rich data for the benefits of our clients. But selling
inspection instrumentation & technology alone in certain very
niche and specialized sub-verticals, such as ILI inspection,
simply doesn't suffice. We are therefore excited to join forces
with NDT Global and work with them and their clients to take
ILI NDT to the next level. "
Along the way, its developments in a variety of magnetic in14

PEC Array Probe + Lyft
A PEC system will use a magnetic pulse to induce eddy
currents in the bulk of carbon steel components. Cutting the
pulse sharply generates eddy currents in the part. The system
listens to the decay of these eddy currents and analyzes
the signal to evaluate the remaining wall thickness. Recent
development in PEC by Eddyfi Technologies has resulted in
a drastic increase in both productivity and detection capabilities
enabling new applications, notes Gabriel Cyr, applications
engineer. An example he describes in a recent blog, available
on the company's website, is how it can be used on ships to
find corrosion in steel deck plates, an application of particular
interest for navy fleets.
Another innovation, employing
Hall effect sensing,
has been to combine
two of its technologies to
elucidate both topside and
bottom-side corrosion in
the floors of steel storage
tanks. The company's
Silverwing Floormap tank
bottom inspection system
combines MagneticFlux
Leakage (MFL) and
Surface Topology Air-gap
Reluctance Sensors
(STARS) to quickly generate
the two views.
Silverwing and STARS discern both
top and bottom corrosion
The technique relies upon strategically placed Hall effect
sensors to detect the magnetic leaking field that is created by
corrosion. On its own, MFL cannot differentiate if the corrosion
is topside or bottom side of the tank bottom. Surface Topology
Air-gap Reluctance Sensors (STARS), however, is a patented
technology that determines whether corrosion is top side
