Movements occur in a pipeline where continuously a media is running through. Among others the movements are caused by:
- Thermal expansions
- Pressure
- Vibrations
- Misalignments
- Foundation deposition
- Movements between other elements.
Depending on the type, design and accessories the rubber compensators absorbs different movements. Either one single movement or a combination of movements can be absorved: |
|
Axial movement
Axial movement is a change in the length of the bellow. Depending on the movements in the pipeline the bellow is either extended or compressed and thereby shortened or lengthened.
The axial movement is also named: Compression and/or extension.
|
 |
Lateral movement
Lateral movement is a parallel displacement of the compensator's ends. One end of the compensator is placed opposite the other. This parallel displacement can be in several different directions (sideways, up/down etc).
This lateral movement is also named: Lateral deviation, parallel not in line, direct displacement or transverse displacement.

Angular movement
Angular movement is characterized by a uniform extension on one side of the bellow and simultaneously a uniform compression on the opposite site. This movement can happen at several levels, but cannot be absorbed in combination. This movement is also named: Rotary motion.
