On the role of vibro-acoustics in leak detection for plastic water distribution pipes
(2017-01-01)
Leaks have been detected and localized in water distribution in many countries for years, by using the cross-correlation of pipe vibration measured either side of a suspected leak and/or by using listening sticks. However, ...
The dynamic behaviour of a buried water pipe and its effect on leak location using acoustic methods
(2013-09-16)
Leakage in buried pipes is one of the main concerns for water companies due to the scarcity of potable water sources. Older metallic pipelines have been replaced by plastic pipes in such systems, which makes it more difficult ...
An investigation into the effects of resonances on the time delay estimate for leak detection in buried plastic water distribution pipes
(European Assoc Structural Dynamics, 2014-01-01)
In water distribution systems, old metallic pipes have been replaced by plastic pipes due to their deterioration over time. Although acoustic methods are effective in finding leaks in metallic pipes, they have been found ...

Wavespeed measurement in buried water distribution pipes and its significance in leak location
(2013-09-16)
To determine the location of leaks in buried water pipes, acoustic methods are often used. These have proven to be very effective in metallic pipes but have been problematic in modern plastic pipes. In this paper the reason ...
Detecting sound waves generated by leaks in buried water distribution pipes
(2017-01-01)
It is common to use guided sound waves to detect leaks or cracks in pipelines. Applications include the nondestructive testing of oil and gas pipelines, which normally takes places at ultrasonic frequencies, as well as the ...
A VIRTUAL PIPE RIG FOR TESTING ACOUSTIC LEAK DETECTION CORRELATORS
(Int Inst Acoustics & Vibration, 2015-01-01)
Acoustic correlators have been used for many years to locate and detect leaks in buried water distribution pipes. Currently, the only way to compare different correlators directly is in the field. This can be problematic ...
