In connection with the increase in oil production in the Far Eastern and Northern regions of the Russian Federation, there is the problem of transporting hydrocarbons over long distances. This is due to an increase in the viscosity of oil at lower temperatures, as a result of which it thickens and the flow rate inside the pipeline decreases significantly. Therefore, along its entire length it is necessary to provide thermal insulation to reduce heat loss. To extend the life of oil pipelines and protect the inner surface from destructive corrosion, the most effective is the use of a protective glass enamel coating. Therefore, the development of a comprehensive technology for the protection of steel oil pipelines in severe climatic conditions is an urgent task for researchers and the petrochemical industry. At the SRSPU (NPI) named after M. I. Platov, within the framework of the RNF project, developed technologies for the synthesis of protective enamel coatings for the inner surface of the oil pipeline and foam glass for its thermal insulation. The article discusses various corrective additives to improve the operational characteristics of materials for comprehensive protection of pipelines. As a result of studies of the effect of corrective additives on the temperature-time synthesis mode and the properties of protective slick coatings for the inner surface of steel oil pipelines and foam glass, used as a heat-insulating material that protects oil pipelines from the negative effects of the environment in harsh climatic conditions, modified compositions have been developed that allow obtaining high-quality enamel coatings and foam glass protection.
The work was carried out at SRSPU (NPI) with the financial support of the Russian Science Foundation under agreement No. 18-19-00455 “Development of the technology for complex protection of oil and gas pipelines operating in the Russian Far East” (supervisor – E. A. Yatsenko).
