(INTEGRITY MANAGEMENT SYSTEM AND ENSURING INDUSTRIAL SAFETY OF GAS PIPELINES WITH DAMAGES)
The article analyzes the directions of improving the integrity management system due to the need to increase the level of safe operation of gas pipelines, as well as methodological support for the examination of industrial safety of gas pipelines with damage associated with the extension of their service life. The relevance of improving the integrity management system is due to degradation processes, in particular corrosion and stress-corrosion processes. It is noted that corrosion is the main factor determining the necessity of gas pipeline overhaul with partial or complete replacement of pipes, and stress-corrosion due to low probability of crack detection, especially in the northern regions, is a determining factor of accident rate. It is shown that the reliability level, which meets the requirements of the Federal Service for Environmental, Technological, and Nuclear Supervision and international standards, can be achieved in the long term if about 20 % of the linear part of main gas pipelines is overhauled.
