Corrugated tube compensator failure mainly corrosion leakage and instability two forms. Through the correct choice of materials and structure for corrugated control, the reasonable design waveform parameter and fatigue life, ensure the installation quality etc, we can improve the corrugated pipe the safety and reliability of the compensator. Corrugated tube compensator are able to in many industry used widely, besides having good compensation ability besides, high reliability is the main reason. Its reliability is the design, manufacture, installation and operation management DuoGe link to ensure that, any link out of control will lead to the service life of the compensator reduce even failure. The author after DuoNian statistics found that cause ripples tube compensator failure reason: design accounted for 10%, 50%, jerry manufacturers installation does not conform to the equipment instructions ask that is occupied 20%, the others by improper operation management.
