Low-carbon steels are the main material for the production of main oil and gas pipelines. Currently, new generation steels of the X70, X80 type are used in global practice, however long-term pipelines are made of 17Г1C steels (X50, X52). Corrosion of the inner and outer parts of pipes is the main factor in the failure of pipelines. The study examines the influence of aggressive environments on the corrosion rate of low-carbon steels of different generations. It was found that for a more aggressive environment the difference in corrosion rate for different steels becomes more significant, and X80 steel showed the best indicators of corrosion resistance in various aggressive environments.
