It is revealed that operating degradation of oil-trunk pipelines steels causes essential deterioration its electrochemical characteristics, a decrease of corrosion resistance in bulk material, sensitivity to stress corrosion cracking and brittle fracture as a result of oil-water medium aggressive action. High effectiveness of the inhibitor NEFGAN-1 for protection against corrosion of oil-trunk pipelines inner surfaces in residual water, diphasic oil-water medium and oil-water emulsion is shown. It is recomended to treat oil trunk-line reserve branches by batch treatment method using the inhibitor NEFGAN-1 and next inhibited oil pumping for its interoperational protection against corrosion.
