INSTALLATION

3 INSTALLATION
3.1 General
We recommend that you use only Edwards flexible pipelines with other Edwards vacuum products. Bellows, flexible
pipelines and braided flexible pipelines are available in different lengths and flange sizes to suit your installation (see
Section 2 ).
3.2 Bellows
Always install bellows in a straight line with both ends rigidly constrained. When installed correctly, the bellows can
withstand a small positive internal pressure, as specified in
Section 2 . Do not use bellows on dry pump exhausts.
3.3 Flexible pipelines
When you install a flexible pipeline, use the shortest possible length and avoid unnecessary bends. Do not use flexible
pipelines on dry pump exhausts.
3.4 Braided flexible pipelines
When you install a braided flexible pipeline, make sure that you observe the minimum bend radius data in Section 2 .
If you do not, the braid will become loose and will no longer support the internal flexible pipeline. This may result
in fracture of the pipeline due to fatigue or overpressure failure.
WARNING
Use the correct flexible component for your application. If you do not, a pressure or fatigue failure
could cause the component to leak and release dangerous process substances to atmosphere.
