The article is devoted to the study of the tie between the physical-mechanical and antifriction properties of polymeric materials. In our work, the dependence of the wear value of polymeric materials on their mechanical properties is presented and the calculated values of linear wear obtained experimentally are given. The obtained dependence makes it possible to predict the wear resistance of polymeric materials in friction pairs with steel in terms of physical and mechanical characteristics by using these characteristics to calculate the amount of wear, select the material of rubbing pairs during design, and assess their suitability for given friction conditions. A wide variety of geographic and operational conditions for the use of oilfield equipment determine various reasons for their failures: deformation and fracture, corrosion damage, wear, and the formation of significant deposits of various substances on the working surfaces of details contained in operational environments. Among the numerous directions for improving the durability and efficiency of oilfield equipment, the most promising is the use of plastic masses instead of non-ferrous and ferrous metals and the isolation of equipment surfaces with thin-layer polymer coatings.
