Abstract

: The process of transporting natural gas through main gas pipelines is carried out under the influence of high pressure, long distances and complex physical and technical conditions. In such systems, the stability of the technological regime directly depends on the accurate and reliable measurement of gas pressure, temperature and flow rate, and the relationship between these parameters is determined by the laws of gas dynamics and hydraulic processes. In practice, most often, accidents in gas pipelines are closely related to disproportionate changes in technological parameters or errors in measurement systems. This article provides a deep scientific analysis of the physical and technical nature of the technological regime in main gas pipelines, the relationship between gas pressure, temperature and flow rate, as well as the main sources of measurement errors that arise during transportation. The equations of state of real gases, the dependence of gas density on pressure and temperature, hydraulic losses and changes in parameters under turbulent flow conditions are theoretically substantiated. At the same time, the possibilities of diagnosing changes in measurement parameters before accidents through correlation analysis were also considered.
