Development of A Method for Assessing the Stress-Strain State of Prestressed Pipelines

The article is devoted to the development of a method for assessing the stressstrain state of prestressed pipelines using the finite element method. This is important for improving the reliability and safety of pipelines exposed to internal and external factors. The technique allows for timely detection of changes in the condition of pipes and taking preventive measures to prevent accidents. The paper analyzes various compensation sections of pipelines under real operating conditions using the ANSYS software package. The results of the study help determine the dependencies of horizontal displacements and stresses in hazardous sections of the pipeline under various loads.
