Abstract

In the oil and gas industry, pipeline is the major transportation medium to deliver the products. MIC has been identified as one of the major causes of underground pipeline corrosion failure and Sulphate Reducing Bacteria (SRB) are the main reason causing MIC, by accelerating corrosion rate. The objectives of this paper is to study the SRB growth namely, Desulfovibrio desulfuricans ATCC 7757 correlating to one of the important environment parameter which is temperature. Thus, a determination of the optimum value for the parameter influencing the corrosion process on the internal pipe of carbon steel grade API X70 is unveiled. This research conducted via laboratory works and One-Factor-at-A-Time (OFAT) method is used for the analysis. The result shows that the SRB growth well at temperature ranging from 20°C to 37°C with the maximum exposure time of 28 days which produce the maximum Cr value of 3.746 mm/year at 37°C. The results in this study prove that the corrosion phenomena on carbon steel by the environment parameter such as temperature and time plays a role in the corrosion process. Furthermore, the study identified that the pitting type of corrosion is detected and accelerated at carbon steel pipe.
