In recent years, after long-term operation of many power plant equipment, it is generally exposed that the position of the pipe support or hanger deviates from the design value. The deviation of the pipe support or hanger will cause stress on the pipe, so that the thrust and thrust of the pipe interface of the equipment The torque increases, and at the same time, the vibration of some pipelines increases. The above situations will reduce the service life of pipelines and equipment. In order to solve the stress and vibration problems on the pipeline, constraints are generally added to the vibrating pipeline. When adding constraints, it is often necessary to adjust the brackets or hangers of the equipment and pipelines as a whole, resulting in cumbersome workload and high manpower and material resources.
