“…Although electrochemical techniques can gain the corrosion current easily and rapidly, they are not suitable for erosion-corrosion monitoring in the field, especially for energy pipelines, due to the inability to directly measure the non-Faradaic part of the metal loss [9,37]. Therefore, electrical resistance (ER) probes as shown in Figure 8 are used to monitor the total metal loss caused by erosion-corrosion in most industrial applications [76,77,[79][80][81][82][83][84][85]. Figure 8a shows a typical erosion-corrosion ER probe with its sensing part in a rectangular form.…”

“…The advantage of an ER probe is that it provides the cumulative metal loss without needing to remove the samples from the service environment. In addition, ER probes are applicable to both conductive and non-conductive erosive and corrosive environments, which suggests both pure erosion and erosion-corrosion can be well probed by the ER technique [83,86]. The major disadvantage of the ER technique is that it cannot respond rapidly to a change of the erosion-corrosion depth loss.…”

This paper firstly provides an overview of major efforts made over the past several decades on developing the test apparatus for the study of erosion-corrosion of ferrous-based steels. The merits and the application range of the set-ups, i.e., rotating disc/cylinder electrode system, slurry jet impingement rig, and test flow loop, are introduced. Secondly, the advantages and limitations of both non-electrochemical and electrochemical methods used for the measurement of erosion-corrosion are presented. Thereafter, the interaction between erosion and corrosion using a cyclic erosion-corrosion method was introduced. The synergy between erosion and corrosion for the steels under the passive state were analyzed on the basis of the breakdown and restoration of the passive film. In addition, the difference between the obtained erosion-enhanced corrosion and the corrosion-enhanced erosion using different experimental methods for steels under active corrosion was discussed. Finally, the interaction between the localized corrosion and erosion was studied through the dynamic change of the local current distribution revealed by the wire beam electrode.

“…As the metal corrodes, the cross-section of the electrode decreases, causing a proportional increase in electrical resistance. ER sensors are one of the most common corrosion monitoring techniques used in different fields, including in the construction industry [ 14 , 15 , 16 , 17 , 18 ], the oil and gas industry [ 13 , 19 , 20 ], the automotive sector [ 21 ], in nuclear waste management [ 22 , 23 , 24 ] and in other, general applications [ 25 , 26 , 27 ]. Despite their popularity, however, they have not been widely applied in the hydrometallurgical industry.…”

Equipment made of different stainless steels is often used in the hydrometallurgical processing industry. In this study, an electrical resistance sensor was developed for monitoring corrosion in acidic solutions at high temperature. Two types of stainless steel were used as the electrode materials, namely grade 316L stainless steel (EN 1.4404) and grade 2507 duplex stainless steel (EN 1.4410). The materials and sensors were exposed to a 10% H2SO4 solution containing 5000 mg/L of NaCl at various temperatures. Results from the sensors were verified using electrochemical techniques and postexposure examination. Results showed that the microstructure played an important role in the interpretation of corrosion rates, highlighting the importance of using an appropriate stainless steel for the production of sensors. Electrochemical tests and postexposure examination both showed that the grade 2507 had a significantly lower corrosion rate compared to the grade 316L. Under industrialprocess conditions, the results for the grade 2507 sensor were promising with respect to sensor durability and performance, despite the extremely harsh operating environment.

“…Various groups have contributed to the knowledge of using transient pressure pulses to detect leak location and quantification [9] [10] [11]. Similarly, methods for blockage or deposit detection [12] [13] [14] [15] and corrosion losses [16], [17] in pipelines and utility piping systems are well documented. For example, Lee et al [18] used an impulse response function to find leaks in pipelines.…”

The use of hydrodynamic pressure wave generated from the action of a fast acting valve as well as acoustic reflectometry in the detection of anomalies like leaks, deposits and blockages in a pipe or fluid flow system in the context of the prevailing scientific theories in fluid flow is discussed. The focus of this paper is the application of the theories to more complex scenarios involving multi-phase fluid flow, specifically, two-phase and two-component fluid flow. The principal concern is the determination of acoustic velocity in a two-phase flow regime; which is problematic because it varies with mixture composition along multiphase flowlines. A technique for simulating flow regimes in the laboratory using stacked S-shaped pipes is presented as well as a discussion of the results from a computational fluid dynamics model.
