This paper is a report on the evaluation of the use of electrochemical corrosion rate probes to detect internal corrosion in natural gas transmission pipeline environments. Flange and flush-mount probes were used in four different environments at three different sites that were selected to represent normal and upset conditions in a gas transmission pipeline. The environments consisted of humidified natural gas, organic/water mixtures removed from natural gas, and the environments at the 6 and 12 o'clock positions of a natural gas pipeline carrying multiphase gas/liquid flow. This paper will summarize and extend results presented previously and add additional data. A re-analysis of previously-reported data will be presented along with the results of physical examinations on the probes. New data on the measurement of corrosion in multiphase gas/liquid environments and for coupons used to determine corrosion rate and to detect the presence of microbiologically-influenced corrosion (MIC) will also be presented.
