Abstract
A 3-week, ambient-temperature hydrotest of storage tanks led to severe pitting of the underside of the aluminum-magnesium alloy floating roofs. Water from a fire water line was used in the hydrotest. Chemical and microbiological analysis of the water and corrosion products, as well as corrosion tests carried out on original and sterilized test water with coupons made of the aluminum alloy, revealed microbiologically influenced corrosion (MIC). The authors suggest that high susceptibility of aluminum alloy to MIC arises from the presence of magnesium - a main alloying element.
