The problem of protection of technological equipment from corrosion is outlined. Possible measures of protection against wandering currents and types of protection against corrosion have been found out. The first is aimed at reducing wandering currents in the ground. The second solves the issues related to preventing the penetration of these currents into technological equipment. There are three types of protection against corrosion: structural, passive and active. An active type of protection against corrosion, in which tread protection is used, is studied in more detail. The disadvantage of tread protection is that the replacement of the protectors requires not only the emptying of the tank, but also its preparation for fireworks, cleaning and degassing, which significantly increases the cost of such a process. Therefore, the implementation of tread protection without fireworks in the tank is investigated, which will allow quick replacement of protectors and introduce protective coatings on existing tanks. Proposed methods of calculation of tread protection against corrosion and their efficiency from commissioning. During the calculation of tread protection, determine the number of treads and their timing depending on the transition resistance of the bottom isolation and the specific resistance of the soil, provided that the protective tensile strength of the tread tank is reached. This technique allows you to determine the final number of treads and their service life in years. Protective protection can be used effectively and instead of lightning protection grounding. The effectiveness of the tread protection located in the tank is estimated by the difference in the potential of the "reservoir-electrolyte" with the copper-sulfate electrode, which is lowered into the reservoir. The requirement is defined, which ensures effective protection of the tread. In order to evaluate the effectiveness of the use of tread protection against corrosion of technological equipment, a scheme of interconnection of the object of evaluation of efficiency with the object being serviced has been developed. The use of this scheme allows us to assert that tread protection increases the efficiency of operation of air fuel supply facilities due to the impact on the system and the operational use of such devices.
