PTFE 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 displacements and installation misalignments, reducing pipeline system vibration.

Installation Precautions for Compensators

1. The installation of the compensator should be carried out according to the pipeline construction drawings and the compensator installation manual.

2. Pipelines equipped with expansion compensators must be properly guided and anchored for the compensators to function effectively. Therefore, the installation of guide and anchoring brackets must be strictly adhered to the technical specifications provided by the design department. For the principles of guide and anchoring bracket installation, 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 by knocking, scratching, sparking, or spatter.

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

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

6. To ensure the bellows is in good working condition, it should not be adjusted using the compensator's deformation, including axial, lateral, and torsional adjustments, to correct installation position errors in the piping system.

7. After the compensator is installed, remove all transport securing bolts painted yellow before the system is operated.
