Article Synopsis
- The study explored methods to prevent avalanche damage to gas pipelines, examining single steel rings and wire winding techniques.
- Reinforcement with single rings effectively reduced crack widths and lengths significantly more than wire winding under varying temperatures.
- The findings emphasize the superiority of using single rings for crack localization, providing valuable insights for engineers and researchers in pipeline design and reinforcement.
In the study, experimental and theoretical studies were carried out to assess the influence of the shapes of dents in the tank wall on the stress-strain state of the defect zone. By testing fragments of a cylindrical tank, it was found that the most appropriate expression is (5), which could take into account the leaching of the tank wall, resulting in a decrease in the stress concentration index. At the same time, during theoretical studies in this paper, it was found that polynomials determined the stress concentration coefficient, where the obtained analytical expression data were compared with the data determined numerically in the ANSYS program, and it was found that the spread was from 2% to 10%.

It is established that when the winding angle changes from perpendicular to the shell axis to 75° and 65°, the circumferential stresses decrease 1.4 times and 1.
