Expansion joints

Externally pressurised axial expansion joints (AE)

Applications where a combination of high pressure and long axial movements exist have resulted in the development the externally pressurised unit.It can be seen that the working pressure is transferred to the outside of the bellows via a gap between the ”rolled and welded” section and the pipe. The unit is complited by a purpose- made outer casing which containes the working pressurre.
