Technology Update
BUILDING on the success of the Corrosion
WheelProbe, a new semi-automated
solution for corrosion mapping applications
has been developed by Sonatest Ltd.
The Veo & Corrosion WheelProbe (CWP)
scanning system is a new enhancement in
response to clients’ requests, providing an
easier way of providing 100% coverage.
The system consists of the veo 16:64, a
phased array flaw detector, a 64 element
Corrosion WheelProbe and a CWP
scanner. The Corrosion Wheel Probe is
a tried and tested solution for corrosion
mapping by many companies in the
pipeline and oil and gas sectors. The scan
width of a Corrosion WheelProbe (CWP)
is close to 50mm in one pass and it can
be used on pipe diameters from 4" to 42".
The conformable tyre allows coupling to
rough surfaces, and the design allows
for consistent, reliable inspection in both
depth and amplitude. This amplitude mode
enhances the possibility of finding small pit
type defects, which do not normally give a
good ultrasonic response, however results
show excellent indications of internal
condition.
The CWP is fitted to an adjustable
connector, equipped with a second encoder,
and allows for multiple adjacent scans with
a good overlap for complete coverage. The
distinct advantage of the CWP Scanning
System is in the relative simplicity and
complete autonomy from the need for
additional power sources on the inspection
site. Ease of portability along with the speed
of set-up and deployment is also a key
advantage for the user in the field.
