Development of corrosion processes under conditions of moisture condensation in the gas phase in the presence of carbon dioxide that lead to formation of local damage are studied. These conditions for creation of a condensation film of water on steel arise on objects for gas production and processing where there are differences in temperature and pressure. It is confirmed that at elevated temperature when the temperature gradient is greater a more significant amount of moisture condenses on a steel surface that leads to an increase in the rate of both overall and local corrosion by a factor of two to three compared to room temperature. The overall corrosion rate is low (up to 0.1 mm/year) and local corrosion with respect to depth index is from 0.9 to 1.8 mm/year. Condensation processes and associated corrosion in aqueous-alcoholic and aqueous-glycolic media in the presence of CO2 depend on the amount of water in these solutions i.e., corrosion does not develop with low concentrations of water.
