Insulation:
It is possible to insulate expansion joints in the same way as
pipework. A protective covering or insulation is essential if the ex-
pansion joint is to be placed underneath plaster.
Start-up:
The maximum permitted testing pressure or operating pressure
must not be exceeded when carrying out pressure-testing or dur-
ing operation.
Excessive surges in pressure
connections, hydraulic shocks and other causes are to be
avoided.
Avoid any corrosive substances intruding into the system.
Maintenance:
Expansion joints must be checked at regular intervals for any
possible leaks or damage.
Check bellows for potential instability.
Inspect the stability of bracings, guides and other components of
the pipework.
Visual inspection of whether the expansion joints are absorbing
dilatations.
Check that no unexpected vibrations occur, whether any signs of
corrosion can be identified.
Check that the bellows convolutions, bracings and pipe routing
are not dirty or the absorption of movement inhibited.
