PR-228-9312-R01 Internal Corrosion Monitoring of Wet Gas Pipe Lines

Describes the results of a literature review to describe the factors that contribute to the internal corrosion of wet gas pipelines and to describe internal corrosion control, inspection, and monitoring techniques. A number of apparently subtle factors can have significant effects on the internal corrosion of wet gas pipelines. The dominant factors are carbon dioxide, hydrogen sulfide, and microbiological-influences. There are a number of other factors that influence the corrosion rate, including temperature, pressure, inhibitor concentration, inhibitor efficacy, inhibitor distribution, water condensation, oil condensate drop out, topography, pigging frequency, and flow rate.
