Corrosion and corrosion-fatigue tests of the material of the pipeline, which was in operation for 41 years. It has been shown that prolonged operation reduces the parameters of resistance to fatigue and prolonged static loading in corrosive environments. It was established that the degradation of physical and mechanical properties is insignificant, Ukraine’s main gas pipelines are ready to operate at full capacity provided that timely monitoring measures are carried out.


One of the ways to increase natural gas production is to conserve and/or intensify existing wells with their subsequent development. They are characterized by a high content of highly mineralized water, which leads to an increased risk of hydrate formation and internal corrosion. The issue of the formation of gas hydrates in industrial pipelines, which is a major problem for the exploitation of industrial gas pipelines, requires considerable attention to be made to exclude emergency situations. The main task of the study – to determine the effect of hydrates on the corrosion of the pipeline in order to prevent emergencies. A technique for studying the effect of hydration on the corrosion of pipelines has been developed. The combined analysis of the corrosion behavior of pipe material in aggressive media of chloride type was done. According to the results of corrosion-mechanical tests, regularities of joint action of mechanical stresses, concentration of chlorides and hydrate formation on the speed and localization of corrosion processes are established.
