IMPROVEMENT OF THE METHOD OF DETERMINING THE LOCATION OF THE FLAW DETECTOR DURING IN-LINE DIAGNOSTICS OF MAIN GAS PIPELINES
(pp. 26-31)

Abstract. The main goal of the study is to improvement a method for determining the location of an in-line diagnostic tool. The method under consideration is based on the use in the calculation of the pressure drop resulting from the location of the flaw detector in the pipe. For theoretical testing of the developed methodology, a calculation model of the pipeline was built using the example of a gas pipeline. The calculation method takes into account both the parameters of the pipeline and the pumped medium, as well as the gravity of the projectile itself, which minimizes errors in determining the coordinates of the defect and makes it possible to eliminate the defect faster and more efficiently. The sections of the article discuss, among other things, general information about the technological reliability of main pipelines, theses proving the relevance of the task, a description of the proposed method for solving it, as well as excerpts from the calculation algorithm, on the basis of which the pipeline model was developed, which allows determining the location of the pig when carrying out in-line diagnostics in this pipeline.

Keywords: flaw detector, defect, diagnostics, inspection gauge, natural gas, main gas pipeline, positioning.
