Abstract: The article deals with the problem of construction and operation of CNG stations and supply pipelines in complex engineering-geological conditions. A key factor in ensuring the reliability of operation is the control of the parameters of the stress-strain state. The accuracy of determining the parameters of VAT calculation methods of gas pipelines limited as the accuracy of the initial data for calculations and imperfection modelling approaches numerical schemes of gas pipelines. In the article, on the basis of numerical and experimental work, the rules for the development of computational schemes, setting boundary conditions and loading conditions of gas pipelines in determining the parameters of their stress-strain state by the finite element method are formulated
