Background

With the development of industry, the application of pipeline systems is wide, and the safety problem of pipelines is always concerned. Many factors affecting the pipeline safety, such as accidental factors including earthquake and unexpected instantaneous impact of external force, and common factors including pipeline vibration and pipeline stress accumulation, all affect the pipeline safety. In terms of pipeline vibration, the serious pipeline vibration not only increases extra power and noise to cause the working condition of a control instrument or an air valve to be deteriorated and failed, but also causes the pipeline structure and pipeline accessories to be fatigued and damaged, and causes serious accidents such as explosion, combustion and the like due to slight leakage and serious breakage. Therefore, it is necessary to pay attention to the vibration-resistant pipe, especially to an important pipe having high temperature, high pressure, large diameter and severe vibration.

In addition to vibration problems, thermal stress (temperature-changing stress) is one of the important factors affecting the safety of the pipe. Generally, when a pipeline is laid, pipeline supports are arranged at intervals, and the pipeline is supported by the pipeline supports to play roles in supporting, positioning and fixing. However, when the temperature of the pipeline changes and the pipeline expands with heat and contracts with cold, the pipeline deforms in the axial direction, the transverse direction and the angular direction, the fixed pipeline support limits the thermal deformation of the pipeline, stress accumulation is easy to generate on the pipeline, the pipeline is easy to break, and potential safety hazards exist.
