The cause of the failure of the bellow expansion joint

2025-01-10

The main reasons for the failure of Bellow expansion joints include the following:
      1. Incorrect insulation measures: During the insulation, the bellows part and the pull plate were insulated, resulting in the failure of the compensator. The bellows part cannot be insulated.
      2. The transport rod is not removed: The transport rod is not removed in time after the installation is completed, resulting in the bending of the tie rod when the pipeline is thermally expanding when the system is not running, and the fixed bracket may be pushed down after the system is running.

      3. Corrosion: Bellow expansion joints may be subject to environmental corrosion during use, especially the environment containing chloride will lead to stress corrosion cracking.
      4. Vibration: The vibration of the pipeline system will lead to the failure of the bellow expansion joint, especially the excessive vibration will aggravate the fatigue damage of the bellows.
      5. Poor design or installation: Improper system design or installation can cause the bellow expansion joint to not work properly, such as improper handling of axial, lateral and angular forces.
