The main cause of leakage in eccentric rubber joints

      1. Non-standard installation: Improper tightening sequence or uneven strength of the rubber joint flange during the installation process may lead to poor sealing and then leakage.
      2. Inappropriate material: If the material of the rubber joint cannot resist the corrosion of the pipeline medium, long-term use will lead to the decline of material performance and eventually leakage.
      3. Unreasonable design of sealing structure: Improper design of sealing structure may lead to uneven and smooth sealing surface between joints and pipelines, impurities and damage, which will affect the sealing effect.
      4. Aging and wear: Rubber joints may lose their elasticity due to aging and hardening during long-term use, and cracks or wear may appear, resulting in leakage.
      5. Uneven pressure: During the operation of the pipeline, if the system pressure is uneven or the instantaneous pressure is too high, it may lead to the rupture or loosening of the rubber soft joints, resulting in water leakage.
      6. Temperature change: In the high or low temperature environment, the rubber joint may expand or contract, resulting in the reduction of the sealing performance of its connection with the pipe, which will cause water leakage.

Options include
      1. Replace the appropriate joint: Choose the appropriate joint material to ensure that its hardness, strength, corrosion resistance and other aspects meet the operation requirements of the pipeline.
      2. Correct installation of joints: During the installation process, ensure that the direction, position, fastening and other elements of the joints are correct, and use suitable sealing materials such as packing, gaskets, etc., to improve sealing performance.
      3. Regular inspection and maintenance: Regularly inspect and maintain the rubber joints, and replace the aging, hardened or damaged joints in time once found.
      4. Control pressure and temperature: Keep the system pressure stable and avoid instantaneous excessive pressure; Use rubber joints that are resistant to high or low temperatures in high or low temperature environments.
