Externally pressurized expansion joints are used where there are large axial movements.
This type of design pressurizes the bellows externally, eliminating column instability concerns for the bellows.
This type of configuration provides an outside cover protecting bellows from external elements and inside pipe acts as a liner
protecting bellows from flow medium and streamlining the flow
