A water phase during the travel in long gas transport pipes will accumulate increasing amounts of Fe/sup 2+/ corrosion product. For a pipeline with an unprocessed well stream of gas, liquid hydrocarbon, and condensed water, the Fe/sup 2+/ buildup in the water phase can have a major influence on the corrosion of carbon steel. The most important effect is that sufficiently high amounts of Fe/sup 2+/ lead to the formation of protecting corrosion films. These experiments were conducted to achieve better insight into the corrosion phenomena occurring in the water phase of a gas pipeline with liquid drop out and no formation water, i.e., with Fe/sup 2+/ and CO/sub 2/ as the main constituents in the water. Most research regarding oil- and gas-related CO/sub 2/ corrosion of carbon steels treats uniform corrosion in absence of FeCO/sub 3/ films. When corrosion rates are predicted from these experiments, rate forecasts tend to become too high because the protection offered by corrosion films is neglected. To improve the situation, the first aspect is to clarify under which conditions films form and then to understand their protecting properties.
