Rohrwerk Maxhütte GmbH –
Germany
Sonatest, an independent manufacturer
of ultrasonic flaw detectors, X-ray
equipment, scanning systems,
thickness gauges, transducers and
NDT accessories, has launched
the new Corrosion Wheelprobe,
specifically designed for pipeline
corrosion mapping applications. Part of
Sonatest’s WheelProbe range, the new,
ergonomically designed model offers
smooth handling, good control and
comfortable grip positions for scanning
around pipes and for easy overhead
work.
Circumferential and longitudinal
scanning are both completed rapidly
and can be performed on pipes with
diameters between 3" and 32". Fast
and easy configuration for different
Pipeline corrosion mapping at speed
pipe diameters is adjustable in the field
thanks to the pipe diameter scale on the
instrument itself, which enables quick
adjustments and fine-tuning.
The CorrosionWheelProbe is compatible
with NDT systems and instruments
from the Sonatest range, such as the
Rapidscan series, and also with a wide
range of industry standard instruments.
Industry sectors where the Corrosion
Wheelprobe can be used include
petrochemical, offshore, oil and gas,
aerospace, composite manufacturing
and marine.
