METHODS, MEANS AND TECHNOLOGY OF VIBRATION DIAGNOSTICS OF MAIN GAS PIPELINES SUBJECT TO STRESS CORROSION CRACKING
(pp. 4-12)

Abstract. Computational and experimental methods, tools and technology for monitoring the technical condition of main gas pipelines during their underground laying according to the parameters of technological and geodynamic vibrations are proposed. To identify potentially hazardous (risk-sensitive) sections of main gas pipelines, the parameters characterizing the microseismic field directly above the gas pipeline routes, the energy forms of natural acoustic vibrations of the natural gas column of the gas pipeline section, the natural frequencies of the pipe of the gas pipeline section as a beam/shell and the soil containing it are used. The results obtained make it possible to reduce operating costs.

Keywords: main gas pipelines, vibration diagnostics, defects such as stress corrosion cracking.
