The question of the possibility of using carbon fiber pipes based on carbon fiber UKN / 5000 (traditional and modified by atmospheric plasma treatment in an acrylic acid environment) as a material of pipelines for the oil industry is considered. The use of carbon fiber pipelines will significantly reduce the weight of the product and increase its reliability during operation. Experimental studies of the strength of carbon fiber pipelines with an internal working pressure of up to 7.5 MPa at a load of 10,000 cycles were carried out. The object of study is the pipeline elements in the form of a pipe with metal bushings at the ends. With the help of metal bushings, samples of the carbon fiber pipeline elements were installed in a laboratory stand to simulate the effect of internal working pressure on the deformation features of the specimen structure. In this case, as a liquid for the creation of internal pressure in the tests the formation water from the oil field at normal temperature (T = 20°C) was used. In order to predict the maximum recuperation of the pipeline made of carbon fiber, internal pressure tests were performed before failure. It is concluded that the efficiency of using carbon fiber for the production of pipelines of the oil assortment is very high. When using modified CFRP, the strength of the oil pipeline element is 20% greater than when using traditional UKN / 5000 carbon fiber as a carbon fiber filler.
