РАЗРАБОТКА ДИЭЛЕКТРИЧЕСКОГО ЭЛАСТОМЕРНОГО ТРУБОПРОВОДА ДЛЯ НЕФТЕГАЗОВОЙ ИНДУСТРИИ

Ensuring the effective functioning of Russia’s domestic pipeline transport market under import substitution conditions is a priority task for the national industry. Developing systems for quick and mobile connections between offshore terminal pipelines and tanker fleets, as well as systems of loading hoses or hoses for other purposes used as oil pipelines, is becoming particularly relevant. However, today potential manufacturers face a serious barrier: the lack of up-to-date relevant national standards (State Standard) and the inability to obtain international certificates. This legal and technical vacuum significantly hinders the implementation of advanced Russian developments at strategic facilities.The situation is compounded by the fact that the manufacturers' local technical specifications do not hold the status of a fundamental governing document for major operators in the fuel and energy sector, whose corporate regulations remain strictly aligned with international industry standards.These factors limit the commercialisation of new products but do not stop the research and development activities of domestic enterprises. For instance, the extensive experience of «Composit LLC» (here in after referred to as «Composit») in the field of hydromechanisation and mining, which served as the basis for this work, enables not only the creation of competitive equivalents to foreign products but also the development of unique items for the oil and gas sector.Within the scope of this study, the manufacturing technology for a dielectric (non-conductive) pipeline has been refined. A comprehensive analysis of the properties of oil-and-petrol-resistant (OBR) rubber compound was carried out, and the optimal adhesive composition for the heterogeneous «rubber-to-metal» system was selected. Laboratory tests of the samples have proven that the developed elastomer maintains high resistance both in hydrocarbon media with oxygenates and without them. It has been established that not all commercially available hot-curing adhesives recommended by manufacturers are suitable for structures of this type. To ensure the monolithic integrity of the product and reliably prevent separation or shear between contacting layers, a differentiated approach to selecting the adhesive composition is required.Based on the experimental data obtained, a pilot industrial sample of a flexible pipeline has been manufactured, recommended for use as part of existing oil pipeline systems.
