“…Seawater has a higher concentration of sulfate than drinking water. Several researches have observed sulphate-reducing bacteria and copper sulfide formation in copper pipes carrying seawater (Chen & Zhang, 2018;Chen, Wang, & Zhang, 2014). This suggests that sulfatereducing bacteria can play a role in copper corrosion.…”

Despite decades of research, the pitting of copper pipes is poorly understood. This article summarizes the key research findings from 1990 to the present and identifies research gaps. Several lines of evidence suggest that, for soft waters, additional alkalinity or maintaining a pH <8.5 may reduce copper pitting. Phosphate corrosion inhibitors, used to prevent lead corrosion, may also moderate copper pitting in low-alkalinity waters. However, such inhibitors could also exacerbate pitting due to insufficient coverage or could increase biological growth. Biological processes are likely involved in pitting corrosion, and practices to reduce biological growth may be beneficial. The research gaps identified include a need for better benchmarking, the effects of chemical transients (e.g., chlorine burns) and of hydraulic transients (e.g., water hammer), and changing the residual disinfectant from chlorine to chloramine.

“…The WBE and electrochemical noise analysis have been used in combinations to achieve earlier detection of pitting initiation activities [39–41], and to determine the kinetics of non-uniform corrosion of mild steel in a carbon dioxide saturated brine [42]. Electrode arrays have also been used in extensive assessment and measurement of pitting in bacteria containing environments where biofilm could form on metal surfaces [43–52]. On the other hand, the WBE was used to assess steel corrosion in multi-phase media such as in water contaminated biodiesel [53,54] and in multi-phase oil/water/carbon dioxide gas media [55].…”

Since the electrochemically integrated multi-electrode array, often referred to as the wire beam electrode, was initially developed for corrosion studies in 1990s, remarkable progresses have been made in its applications for probing and monitoring various forms of localised corrosion that are difficult-to-measure by conventional methods. This paper provides a brief overview of diverse and innovative applications of variously designed and constructed electrode array probes for measuring localised corrosion under complex environmental conditions with particular focus on the discussion of challenges and obstacles that prevent wider applications of electrode arrays. Discussion on future perspectives have included suggestions on the innovative design and fabrication of multi-scale, three-dimensional, complex shaped and patterned electrode arrays for simulating microstructural features of heterogeneous alloys and thoughts on the future integration of corrosion monitoring data and data analytics, machine learning and artificial intelligence for future prediction, modelling and prevention of corrosion in industrial applications.

According to Chen and Zhang (2018), Lv et al (2020), SRB interfered with the electrochemical reactions that happened during polarization, increasing the cathodic current. Chen et al (2021bChen et al ( , 2021c realized that as the strain rate increased, the rust layer was destroyed, resulting in a decrease in passive film resistance.…”

Purpose The purpose of this study is to find the multi-factor influence law of stress, strain rate and sulfate-reducing bacteria (SRB) on X70 pipeline steel in a simulated solution of sea mud and the order of influence of the three factors on X70 steel to develop a scientific basis for pipeline corrosion protection. Design/methodology/approach This paper studied the effects of stress, strain rate and SRB on the X70 pipeline steel corrosion behavior in simulated sea mud solution through orthogonal testing, electrochemical experiments and morphological observations. Findings The results of this study showed that stress proved to be the most relevant element for corrosion behavior, followed by SRB and strain rate. At high stresses (301 MPa and 576 MPa), stress dominated the corrosion behavior of X70 pipeline steel. However, at low stress (82 MPa), SRB played the most important role. Originality/value Subsea pipelines are in a very complex environmental regime that includes stress, strain rates and SRB, which often cause pipeline pitting and perforation. However, most scholars have only looked into the influence of single factors on metal corrosion. So, the single-factor experimental results of previous studies could hardly be applied to actual working conditions. There is an urgent need to understand the multi-factor influence law of stress, strain and SRB acting together on the pipeline corrosion behavior, especially to determine the dominant factor.
