Ultrasound is a great technology
for trouble shooting internal
hydraulic leaks, blockages, and
bypasses. Sidney Hand of Koch
Cellulose in Brunswick, GA
recently called to tell us how
their Ultrawave SDT170 found an
internal leak on a grappler
hydraulic stop valve. The
grappler is used to transport
tons of timber through the mill
and any malfunctions pose
serious safety issues.
To test hydraulic cylinders on a
grapple bucket they used the
following procedure:
Position grapple bucket in
working platform so that all
four stop valves can be reached
with detection equipment. With
electric hydraulic pump
pressurizing system, have
operator close grapple.
Ensure SDT Ultrasonic Detector
is set to the US sensor setting
(internal leak setting).
Position the SDT contact probe
on the stop valve body and then
instruct operator to pressurize
system once again by
continuously forcing the grapple
into the closed position.
Observe the amplitude bar scale
and value on the SDT Detector.
Note: An amplitude fluctuation
of approximately twenty decibels
indicates a properly seating,
non-leaking stop valve.
With SDT headphones, listen for
either a continual or
fluctuating hissing sound. A
continual hissing sound combined
with a constant amplitude value
means that the stop valve is
leaking pressure.
Visit the SDT Ultrasonic
Learning Lab at IMC-2004 and
learn about ultrasound
inspection. Meet ultrasound
experts from around the globe
and find the answers to all your
questions about ultrasound
inspection.
Application based presentations
will run for the duration of the
conference. Individual work
stations will expose you to all
the applications for this wonder
technology.
Learn how to perform:
• leak detection
• bearing monitoring
• condition based lubrication
• tightness testing
• underground
• storage tank testing
• electrical inspections
• steam trap inspections
• time waveform and spectrum
analysis
• on-line leak monitoring
Find out how to:
• Implement an effective
ultrasound program
• Get the most out of your
ultrasound program
• Benchmark your ultrasound
program
• Take your ultrasound program
to the next level

Presentation on ultrasonic leak
testing of underground storage
tanks. Jan Verhofstadt of SDT
International has spear-headed a
program in Europe where over
10,000 underground tanks had to
be certified tight.
At the heart of this initiative
was the SDT Tank Test. Learn how
this government driven project
was managed from start to
finish, leaking tanks were
identified, and soil
contamination avoided. The
deadline for this program was
short, and the consequences of a
bad diagnosis would prove
disastrous. We’ll see you at the
United Nations of Ultrasound
user group meeting for a thought
provoking demonstration about an
environmental disaster averted.

Ever wonder how Electrical
Inspections are done in Brazil?
Do you have a corporate
initiative to reduce compressed
air but trouble getting everyone
to "buy-in"? The Ultrasound User
Group Meeting will solve these
and other problems that impede
effective ultrasound programs.
