With a total capacity of initial processing of 51-54 million tonnes of oil per year, the pipelines are corroded for 3-4 years during the maintenance-free service life. Lately, much attention is given to developments, related to anticorrosion protection methods of oil-and-gas pipelines, run in soil with different level of mineralization, in swamp, uliginous soils, containing sulfate-reducing bacteria, using development of mix of new composition of corrosion-resistant coating. Traditionally, the ground, atmospheric  and other types of corrosion protection provide with effective selection of insulation coating in combination with cathodic protection (e.g. rolled plastic covering). However, the results of these developments have a variety of disadvantages, since the adhesion and corrosion-resistant characteristics as well as complicate technology of using and high price of materials are uncovered. The work offers energy-efficient technology for repairing oil pipelines with a diameter of 146 mm using, bandages made of glassplastic on the basis of fiberglass RT 800 and epoxy connector using selective infrared radiation. Bandage was applied on the model of pipeline with hand lay-up. To reduce   for pipeline repairs it is proposed to use device with infrared rays during polymerization bandage. The source of infrared radiation is halogen lamps, inertia of which is six seconds. During testing with internal pressure, pipeline with bandage lost impermeability at value of internal pressure, which is equal about 7.6-8.0 MPa. This is 5 times higher than operational pressure of pipeline with diameter of 146 mm which is equal 1.5 MPa. ER -
