... rotation on convex sections of the pipeline. Taking into account the random nature of the excess internal pressure p, the sample of the actual values of which were obtained at the pipeline operation stage, the strength of the curved sections of the main pipeline was evaluated. The necessity of individual selection of the weight of a single weight for each section of the pipeline is justified taking into account the specific law of distribution and the limits of dispersion of internal pressure in ...

... The paper presents the results of studies of the mechanical properties of the material of pipes made of 17G1S steel by various manufacturers of tubular products, and an assessment of the influence of these properties on the strength reliability of main pipelines. Results processing of studies for mechanical characteristics of pipe steels and the calculation of the probability of failure-free operation of main pipeline linear sections according to the strength criterion are based on the mathematical ...
