Axial expansion joints

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.
