Polytetrafluoroethylene bellows compensator (also known as an expansion joint) is an industrial instrument used in pipeline systems for corrosive media to compensate for thermal expansion and contraction displacement and installation misalignment, and to reduce pipeline vibration.

Installation Precautions for Compensators

1. The installer should follow the piping installation drawings and the compensator installation manual.

2. The pipeline installing the compensator must be properly guided and secured for the compensator to function effectively. Therefore, the setup of guiding and securing brackets must be strictly adhered to the technical documents provided by the design department. For the principles of setting up guiding and securing brackets, please refer to the "Wavy Compensator Installation Guide."

3. The bellows used in compensators are formed from thin-walled stainless steel plates. Therefore, during transportation, lifting, and welding, it is important to avoid damaging the bellows due to impacts, scratches, arc striking, and welding spatter.

4. Prior to installation, remove any foreign objects from the bellows and piping to ensure the bellows operate normally.

5. Compensators with directional requirements should be installed according to the direction of the medium flow arrow.

6. To ensure the bellows is in good working condition, installation should not use the deformation of the compensator, including axial, lateral, and torsional adjustments, to correct the installation position errors of the pipeline system.

7. After the compensator is installed, all transport fixing screws painted yellow should be removed prior to system operation.
