Description

Technical Field

[0001] The utility model relates to the technical field of corrugated compensators, and more specifically, to a corrugated compensator with a deviation indicator. Background Art

[0002] The advantages of the corrugated compensator in the market are obvious. It has the advantages of pressure resistance, crack resistance, corrosion resistance, easy installation, etc. It also has good flexibility and sawability, which is convenient for processing. In recent years, with people's attention to environmental protection and energy conservation, the demand for the corrugated compensator market has further increased, and its application is relatively common, including indoor and external energy medium pipes, water supply and drainage projects, etc. The corrugated compensator pipes on the market currently have corrugated structures inside (outside) the pipes. The wavy structure formed inside (outside) the corrugated compensator makes the pipe have a better medium density when carrying the same flow rate, and also enhances its strength and stability. During use, the corrugated compensator has good flexibility and scalability, which is used to resist the influence of external forces and its own stress, so as to better protect the pipeline and pipeline system.

[0003] At present, when dealing with stress deformation, the bellows compensator mainly uses the flexibility and elasticity of the corrugated structure to deform, thereby reducing the impact and vibration of external forces and ensuring the installation and stability of the pipeline. In principle, by performing stress analysis on the pipeline and measuring the strain value on the surface or inner wall of the bellows compensator, the stress value is calculated, thereby analyzing the pressure state of the pipeline. By attaching radioactive materials at both ends of the bellows compensator and using a radioactive measuring instrument to measure the bending angle of the pipeline, the degree of deformation of the pipeline can be detected. The bellows compensator is subjected to pressure deformation test and tensile test, and the deformation amount and maximum deformation value of the pipeline are numerically calculated to evaluate the safety status of the pipeline.

[0004] In actual application, the above-mentioned detection means require professional stress analysis instruments and technicians, which are costly, and this detection method cannot monitor the bellows compensator in real time. At the same time, when using this measurement method to test the bellows compensator, it will cause a certain degree of impact on the on-site production activities, affect the smooth progress of production, and reduce production efficiency.
