Detection of Partial Blockages in Pressurized Pipes by Transient Tests: A Review of the Physical Experiments

Pressure waves, while traveling along pressurized pipes, collect precious information about possible faults (e.g., leaks and partial blockages). In fact, the characteristics of pressure wave reflected by fault are strongly related to it. To encourage use transient test-based technologies (TTBTs) for blockage (PB) detection in pipe systems, it can be interest critically analyze available experimental results point out aspects that need investigated more detail, since no review has been executed so far. Such a deficiency two negative consequences. The first one is TTBTs still relegated limbo technicians. second not enough material refining tools extract all contained acquired signals then pursue an effective PB detection. As main analysis, following issues counted: (i) lack tests carried large diameter concrete pipes; (ii) absence complex systems looped networks); (iii) extreme considering real systems. fulfillment last issue will greatly contribute solutions other ones.
