Losses from corrosion of metal equipment include both direct costs associated with repairing and replacing damaged structures, as well as indirect costs associated with reduced productivity and operational efficiency of equipment, as well as a shortened service life of structures and machines. Research and development in recent years confirm the significant potential of conservation compounds for metal corrosion protection. Furthermore, current trends point to the need to transition from traditional products to biodegradable ones. This article examines the results of studies of conservation fluids based on T-22 T-46 and T-1500 mineral oils and plant-based bisimidazoline corrosion inhibitors for long-term protection of metal equipment from atmospheric corrosion. An important aspect of the research is the compatibility of bisimidazolines with the main components of mineral oils, which provides comprehensive corrosion protection during conservation. Depending on the mineral base, composition and amount of inhibitor used, the anticorrosive efficacy of the conservation compounds varied, clearly exceeding the stated standards for absolute protection. Deep synergy, high efficiency and compliance with modern environmental requirements were established for the studied conservation compounds.
