“…This feature confirms that the increase of the damping is a clear sign of the presence of a fault. However, it is very hard to extract a clear information about its type, as discussed in Brunone et al (2018) and Capponi et al (2020). Accordingly, the determination coefficient drastically decreases in the long term ( Figure 14a).…”

This paper concerns the use of Transient Test-Based Techniques (TTBTs) for fault detection in a long transmission main. It reports the results of two series of transient tests executed in a real and operating pipe system. Because of the complexity of the investigated pipeline that includes several stubs, different pressure wave generators were used at both the end sections. Precisely, transients were caused by a pump shutdown and the Portable Pressure Wave Maker device. The analysis of the results shows that, according to the characteristics of the transient tests and the investigated system, only a part of the system can be explored properly from a given generation point. The proposed test procedure allows overcoming the negative effect of a change in the initial and boundary conditions. In fact, contrary to laboratory, in a real system, it is quite impossible to repeat tests in the same flow conditions. The success of the surveywith two leaks detected with a good precision-confirms the potential of the TTBTs for fault detection in real systems. MENICONI ET AL.

“…As one of the many problems faced in piping systems, leakage and blockage can be caused by different physical and chemical processes in pipelines and pipe networks, ultimately resulting in failure, energy loss, and reduced system efficiency. Transient flow and its application as a method of assessing the effects of leakage and blockage in piping systems can be found in Stephens et al (2002), Adewumi et al (2003), Haghighi & Ramos (2012), Meniconi et al (2012), Tuck et al (2013), Duan (2016Duan ( , 2018Duan ( , 2020, Duan et al (2014Duan et al ( , 2017a, Capponi et al (2017Capponi et al ( , 2020, Zhao et al (2018), Louati et al (2018), Rahmanshahi et al (2018), Keramat & Zanganeh (2019), Zouari et al (2020), Zhang et al (2020), andPan et al (2021). Stephens et al (2002) conducted field investigations and used transient flows to identify the blockages in a long pipeline as part of a piping system composed of pipelines, branches, and loops.…”

In this study, transient flow and partial blockage in polyethylene (PE) pipe network are investigated experimentally and numerically using the method of characteristics in the time domain considering pipe-wall viscoelasticity. The experiments were conducted on a PE pipe network with and without partial blockage. The experimental pressure signals were damped during a short period of time in the blockage-free case. The numerical model was calibrated by the inverse transient analysis (ITA). The hydraulic transient solver calibrated with one Kelvin–Voigt element showed good consistency with the experimental results. Partial blockages with different lengths and sizes were examined at different locations of the pipe network. Results reveal an increase in head loss, pressure signal damping, and phase shift with increase in blockage. In addition, the location and characteristics of blockages with different sizes were determined using the ITA in the pipe network.

“…TTBT is an inexpensive measurement technique that requires only a few minutes for the test [ 9 ]. Another advantage is that the leaking size, location, and the initial pressure can be determined by analyzing the pressure signal only [ 33 ]. A network of distributed pressure sensors and thermometers on the external pipe walls can detect pipe failures.…”

The real-time monitoring of fluid properties in tubular systems, such as viscosity and flow rate, is essential for industries utilizing liquid mediums. Nowadays, most studies of the fluid characteristics are performed off-line using laboratory facilities that can provide accurate results, yet they do not match the demanded industrial pace. Off-line measurements are ineffective and time-consuming. The available real-time monitoring sensors for fluid properties are generally destructive methods that produce significant and persistent damage to the tubular systems during the installation process. Others use huge and bulky invasive instrument methods that generate considerable pressure reduction and energy loss in tubular systems. For these drawbacks, industries centered their attention on non-invasive and non-destructive testing (NDT) methodologies, which are installed on the outer tubular surface to avoid flow disturbance and desist shutting down systems for installations. Although these sensors showed excellent achievement for monitoring and inspecting pipe health conditions, the performance was not convincing for monitoring the properties of fluids. This review paper presents an overview of the real-time monitoring of fluid properties in tubular systems for industrial applications, particularly for pipe monitoring sensors, viscosity, and flow measurements. Additionally, the different available sensing mechanisms and their advantages, drawbacks, and potentials are discussed.
