In this work, the maximum potential difference on the surface of the pipeline while in contact with various phases of the oil-water emulsion was established. Potential measurements were made under static conditions in a medium that simulates the separation of water in the pipeline, on the metal surface of a piece of steel pipe 20. The study showed that the controlling step of corrosion is differential aeration, which contributes to a significant potential difference in the surface of the metal in contact with the different phases of the oil-water emulsion. The potential difference in different sections of the metallic surface in corrosive medium No. 3 varied from 0,3 to 0,5 V, which meant the development of a galvanic cell, and that the anode section is formed on the metallic surface located in the accompanying oil water.
