The main use of the unique properties of rubber compensator. Such as high flexibility, high air tightness, medium resistance and weather resistance and radiation resistance etc. The polyester cord oblique high strength, thermal stability and high pressure, high temperature die after review by cross linking and. Internal high density, can bear high pressure, elastic deformation effect is excellent. The product structure design section camber, curve length, has a unique function of multi-directional larger. 
    During the operation of the compensator failure mainly for the corrosion leakage and buckling deformation in two forms, among them the majority with corrosion failure. 
    The corrosion failure of bellows expansion joints (compensator) anatomical analysis, corrosion failure usually point corrosion and stress corrosion cracking, where the chloride stress corrosion cracking about the corrosion failure 95%. Therefore, the correct choice of bellows material and structure, reasonable waveform parameter and fatigue life, designed to ensure installation quality measures, can greatly improve the bellows expansion joint (compensator) safety and reliability. The design should consider the compensator, stability, prevention of bellows. 
    Data shows, corrugated tube compensation depends on its fatigue life, fatigue life of bellows is high, single wave compensation is small. When the allowable lower life of bellows design, not only the meridional stress is high, the circumferential stress is relatively high, the bellows part soon enter the plastic deformation, causing the bellows instability caused by failure.
