“…Metallic materials used in the geo-energy industry are susceptible to different forms of corrosion, such as general and localized corrosion, and pitting (Dariva and Galio, 2014;Streicher, 2011). Localized corrosion mainly caused by biotic factors, also known as Microbial Influenced Corrosion (MIC) is a major cause of pipeline leakage (Alabbas and Mishra, 2013;Clarke and Aguilera, 2001;Li et al, 2018). MIC is a problematic type of corrosion because MIC is difficult to identify compared to abiotic corrosion.…”

“…MIC is a major challenge to many industries including oil, gas and mining [ 5 ]. Approximately up to 40% of all internal corrosion failure in oil pipelines are due to MIC [ 6 – 10 ] causing huge financial losses in the order of billions of US dollars [ 11 ]. Although there are numerous kinds of bacteria involved in accelerating the corrosion of materials, anaerobic sulphate reducing bacteria (SRB) are the chief culprits.…”

Corrosion under flow conditions is a major problem in the transportation industry. Various studies have shown the direct impact of different flow rates on bacteria biofilm formation, mass transfer and resulting different corrosion behaviour of materials in neutral environments. However, little is understood on corrosion under acidic flow conditions. This study investigated the impact of an acidic artificial seawater environment containing Desulfovibrio vulgaris on DSS 2205 microbial corrosion under different velocities (0.25 m.s-1 and 0.61 m.s-1). Experiments containing no bacteria were performed as controls. Bacterial attachment was observed by optical and scanning electron microscope (SEM). Materials corrosion was assessed using open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. Pits formed after potentiodynamic test were observed under SEM. The largest area of bacterial attachment was found on coupons immersed at a velocity of 0.25 m.s-1; however, the corrosion rate was lower than at higher velocity. Shallow pits occurred in the metal coupons when bacteria were present, while deep pits occurred in the controls. The study indicates the positive impact of biofilm formation in corrosion prevention of materials under acidic condition. The nature of corrosion behaviour of duplex stainless is discussed.

“…Some microorganisms can survive inside hydrocarbon pipelines because the basic needs for life are still available: water, carbon, electron provider and acceptor (Alabbas & Mishra, 2013). The micorbes break down molecules to what they need to make energy and in the process flow electrons to the piping (Alabbas & Mishra, 2013). This creates localised anodes and promotes corrosion (Alabbas & Mishra, 2013).…”

This creates localised anodes and promotes corrosion (Alabbas & Mishra, 2013). The more bacteria that build up in a biofilm the more aggressive the corrosion (Alabbas & Mishra, 2013).…”
