What is pipe stress? Pipe stress refers to the forces acting on a pipe from both the inside and outside. The main types of pipeline stress include the following: Internal pressure stress in pipelines: This refers to the internal pressure exerted by the medium within the pipeline, or the inertial force generated by the flow of that medium. Its magnitude changes depending on the type of medium and the flow rate within the pipeline, reflecting the changes in the working conditions of the medium inside the pipeline. External pressure on pipelines: refers to the pressure exerted by materials such as soil or water flow outside the pipeline; its magnitude is influenced by factors such as the depth of burial of the pipeline, geological conditions, and the environment. Pipeline stress – thermal stress: The stress that arises due to temperature changes, which cause the material of the pipeline to expand when heated and contract when cooled. Thermal stress usually occurs during the installation, operation, or cooling down of pipelines. Pipeline stress – bending stress: The stress resulting from the bending and deformation of the pipeline due to its non-linear path or external forces acting on it. Pipeline stress – compressive stress: The stress generated as a result of the pipeline shortening due to factors such as heavy loads. Pipe stress – Gravitational stress: The stress generated as a result of the gravity acting on the pipe in the vertical direction. Pipeline stress, segmental stress: refers to the stress that occurs at the junctions between two pipe segments that are in relative motion, either at the ends of the pipeline or within the same segment. Pipeline stress can have an adverse effect on the safe operation of pipelines; therefore, it is necessary to analyze and monitor pipeline stress in order to identify and resolve potential problems promptly.
