“…Bilobran. It should be noted that the research papers [22,23] investigated the influence of operation parameters of a non-gas pipeline on its flow capacity, and the works [24,25] describe the stresseddeformed state of line part of gas pipelines, problems of forecasting durability of pipelines due to low cycle stresses were considered.

The operating conditions of main pipelines are analysed and it is established that fatigue and corrosion damage are the main causes of their destruction. The paper provides a substantiated answer to the question of the effectiveness of repairs using overlay elements. The number of load cycles that will take place before the destruction of the emergency section after repair with the use of overlay elements is determined by an example.

“…Failures, as a rule, arise under the influence of two groups of factors: a reduction in the bearing capacity of the pipeline under the influence of local defects, which are stress concentrators, and a pressure increase due to unsteady operating modes. The influence of various factors on the serviceability of main gas pipelines is uneven [1]. Avalanche failure is especially dangerous for pipes [2].…”

The dynamic stress–strain state and fracture of a steel main gas pipe section between supports with a straight-through crack was analyzed with consideration of the temperature effect on changes in the mechanical properties of the pipe material. The numerical solution of the problem was implemented in the ANSYS-19.2/Explicit Dynamics software package. The process of fracture in a section of the gas pipeline “Beineu–Bozoy–Shymkent” with a linear crack in the temperature range of −40 °C to +50 °C at the operating pressure of 7.5 MPa and critical pressure equal to 9.8 MPa was considered. As a result, it was found that at the initial growth of the internal pressure from working pressure to critical pressure, the length of the crack doubled. At the same time, the process had a local characteristic. Further development of the crack had the nature of avalanche fracture and depended on the temperature of the steel pipeline. With increasing temperature, there was also an increase in the length of the crack at the avalanche fracture. Thus, at a temperature of 40 °C, the crack lengthened 67.75-fold; at a temperature of −10 °C, the crack lengthened 68-fold; at a temperature of +20 °C, the crack lengthened 68.25-fold; and at a temperature of +50 °C, the crack lengthened 68.5-fold. In this work, this difference was 75% of the initial crack length. This fact will be used for further development of the technique of strengthening damaged pipe sections using bandages.
