Share Visual & Sounding Inspections
Visual and sounding inspections are a reliable method of detecting pipes in an advanced state of distress.

These internal inspections require manned entry to the pipeline and require the pipe to be dewatered. Typically a visual and sounding inspection is conducted in parallel with an electromagnetic inspection. Using the data from both inspection methodologies, our Engineering Services can deliver an accurate report on the condition of the pipeline.
Visual
The visual inspection involves a field team internally traversing a pipe to visually inspect for evidence of a loss of prestressing a pipe section (e.g. longitudinal cracks consistent with wire break damage) and other problems that may be apparent. While this inspection is performed, typically a sounding inspection is also performed.
Sounding
The sounding portion of these inspections rely on impacting the interior surface of the pipe wall with a tapping rod and listening for hollow sounds indicative of delamination. Delaminations are also an indication of a loss of prestressing in a pipe due to wire break damage.
