The technical security and environmental situation of the oil and gas pipeline are depending on the durability and reliability of machines and equipment used in the oil industry. Piston pumps and compressors are widely used for the exploration and transportation of oil and gas. Piston and centrifugal machines are heavy-duty systems that are still failure-prone due to high stresses and wear proses. Specialized methods will be developed for the influence of impacts, vibrations, temperature, and film lubrication and unified in a system model. The research efforts will lead to more reliable and efficient design alternatives for reciprocating machines which are used for the transport of oil and gas and will thus contribute directly to the competitively of a key industry in the Caspian Sea - Black Sea Region, for example in Baku-Tbilisi-Ceyhan (BTC) Main Oil Pipeline, there are 8 pump-compressor stations (2 stations in Azerbaijan, 2 stations in Georgia and 4 stations in Turkey territory). The durable and reliable work of piston machines and their technical security have great practical importance in reducing the environmental impact of hydrocarbon transport. Investigation and control of the dynamic processes of these machines are current problems for oil and gas transportation. Piston and centrifugal compressors are heavy-duty systems that are still failure-prone due to high stresses and wear proses. Specialized methods will be developed for the influence of impacts, vibrations, temperature, film lubrication, and a unified system model. The research efforts will lead to more reliable and efficient design alternatives for reciprocating machines which are used for the transport of oil and gas and will thus contribute directly to the competitiveness of a key industry in the Caspian Sea - Black Sea Region. The article investigated the main causes of failures through the collection and analysis of data from different parts of the machines used for transporting the oil and gas resources. The stress and deformations are analyzed for the piston group made of steel material or special aluminum alloy by applying pressure on it in structural analysis in this article. Structural analysis was performed in ANSYS software. An analysis of static stress and damages due to the application of pressure is presented and analyzed in this work. By observing the analysis results, we can decide whether our designed piston is safe or not under applied load conditions. The durable and reliable work of compressor-pump stations used in the oil and gas industry has great importance for practice. Investigation of complex problems with respect to friction and wear (clearances), stresses, and strain phenomena in the piston of piston machines gives the opportunity to solve the problems of increasing the durability of these machines, method of increasing their mechanical properties has been developed in this article. The dependence of wear intensity on the mechanical characteristics of friction materials is determined. The tribotechnical characteristics of specific materials have been investigated, friction and wear intensity diagrams have been plotted depending on the sliding velocity. The results of the study can be useful in the development and operation of machines and 3equipment used in the oil and gas industry.
