The metal bellows expansion joint compensator must be designed to accommodate vibration, expansion, and bending. Given that the metal surfaces are irregular and considering the effects of vibration, expansion, and bending, traditional coatings like paint are prone to failure. Using VCI (Volatile Corrosion Inhibitor) vinyl or silicone-based flexible damping materials exhibits excellent elasticity. By encapsulating the metal bellows expansion joint compensator with VCI vinyl or silicone-based materials, especially with transparent encapsulation, we can effectively prevent moisture, oxygen, and other corrosive agents from damaging the metal bellows expansion joint compensator on-site. Additionally, this encapsulation helps dampen vibrations, expansions, and bending, thereby reducing mechanical fatigue. It also serves to seal any damaged bellows expansion joints, preventing leakage of fluids that could impact employees and the environment.
