An urgent issue in the operation of Bovanenkovo-Ukhta gas pipelines in conditions of frozen and seasonally thawing soils is the refinement of parameters of anticorrosive electrochemical protection of gas pipelines. The article discusses the process of determining corrosion activity of water samples that differ in the degree of mineralization during sequential cooling to freezing using the polarization resistance method using an FT-360-40 liquid cryostat and IPC-pro potentiostat with a set of working and auxiliary electrodes.
