One of the promising directions of the use of expansive cements is making the protective bandages for the maintenance of pipelines. Bandages expansive application of the compositions of the pipeline reinforce the damaged area and reduce stress due to compressive stress in the cylindrical area. Such requirements are best suited for expansive compositions obtained from portland cement and modified quicklime. The article presents the results of expansive cements based on quick lime in order to implement protective bandages pipelines.


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.
