Axial expansion joints
- Axial expansion joints compensate assembly tolerances and thermal longitudinal expansion in the direction of the tube axis.
- Depending on the design, they can be impinged with pressure internally and externally.
- Using a guide sleeve protects the metal bellows from abrasive media or flow-induced oscillations.
- The reaction forces caused by the internal pressure must be absorbed by sufficiently dimensioned anchor points.
Universal expansion joints
- Universal expansion joints absorb axial, lateral and angular movement simultaneously.
- Installation is primarily in the low pressure area.
- Using a guide tube protects the metal bellows from abrasive media or flow-induced oscillations.
- The reaction forces caused by the internal pressure must be absorbed by sufficiently dimensioned anchor points.
