Buried corrugated compensator mainly used in buried pipe axial compensation, has super anti-bending ability, so buried compensator shell can freely expansion compensation under the protection of sleeve.

Application: Pipes with axial displacement by temperature or pressure changes

Heating and air conditioning installation

Hot water and fire protection system

Compressors inlet and outlet

Diesel engine sets/Pipelines/Turbines/Blowers/Vacuum pumps/Heat exchangers

Installation notes

1. Set fixed bracket to prevent pipe stretching outside influenced by inside pressure.  

2. One end of compensator should close to fixed bracket, use the moving head to compensate pipeline.  

3. According to the compensation amount to set the distance between two fixed brackets, compensation amount is no more than pipe diameter.  

4. Compensator should not appear the tensile phenomenon during pressure test.

5. The compensator&Metal expansion joints absorb movement in piping caused by theraml changes.

6. Durability and excellent chemical resistance.

7. Widely used to absorb termal expansion in pipe systems carring water, steam, oil and gases
