Abstract
Microbial corrosion of the external surface of carbon steel pipes was investigated using sodium tungstate, sodium nitrite and zinc nitrite as individual and combined inhibitors. The study involved carbon steel pipes in contact with Acidithiobaccillus thiooxidan. Inhibitor efficiencies were determined and the optimum inhibitor concentration required to effectively limit the corrosive effect of the microbe was 51–52 g/L for the best inhibitor. Also, despite the limiting effect of sodium nitrite in its other inhibitor formulations, its presence in the mixture of all three components, improved the performance of the other two chemicals giving the best inhibition efficiency of 85.68%.
