Effectiveness Assessment of Pipe Systems by Means of Transient Test-based Techniques

In this paper, the reliability of transient test-based techniques for detecting pipe system anomalies is shown by means of numerical and experimental tests – both in laboratory and real pipe systems – with particular regard to the case of a partially closed in-line valve. With regard to the analysis of pressure signals, attention is focused on the time domain approach. Moreover, the optimal modality of transient test execution is discussed. References concerning the diagnosis of other anomalies (e.g., leaks, partial blockages, and illegal connections) by means of transient tests are also included for the interested reader.
