The issues of improving the methods of calculation and design of the gas transmission system (GTS) are considered, taking into account the analysis of loading modes and peculiarities of its individual nodes. The analysis of design schemes for evaluating the performance of elements of the gas transmission system according to the strength criterion is given, and a probabilistic method for assessing the reliability of butt welds of pipelines is selected. The features of the operating conditions of the system are considered and the method for calculating equivalent strength indicators and loading modes is presented. A unified approach is applied for determining the probability level of failure-free operation of parts and components of a structure. A comparative analysis of traditional and new methods for assessing the performance of the considered system is given. The interval values of the parameters included in the dependence to determine the probability level of a failure-free operation of a welded joint are clarified. A computational method is proposed, which allows to increase the carrying capacity of the GTS in the probabilistic aspect.
