A study on the influence of the composition of the model media of the soil electrolyte (NS1–NS2) on the corrosion rate of tubular steels 17G1S and 13G1S-U in a long-term experiment. The phase composition and structure of corrosion products were determined by X-ray analysis. using an X-ray diffractometer Shimadzu XRD-7000. It was found that, regardless of the steel grade, the composition of corrosion products in the environment of NS1 will be mainly characterized by the presence of lepidocrocite, and in the environment of NS2 – goethite. The corroding samples in both media will have a small amount of magnetite. During the exposure (609 days) of steel samples in the studied model media, the rate of corrosion processes depends on the component composition of the model media, steel grade and pH. The obtained results are important for predicting the behavior of underground pipelines in soils of different corrosive activity.
