1 INTRODUCTION
1.1 Scope and definitions
This manual provides installation instructions for the Edwards range of bellows, flexible pipelines and braided flexible
pipelines. The Item Numbers for the products are listed in Section 2. You must use the bellows, flexible pipelines and
braided flexible pipelines as specified in this manual.
Read this manual before you install the bellows, flexible pipelines and braided flexible pipelines. Important safety
information is highlighted as WARNING and CAUTION instructions; you must obey these instructions. The use of
WARNINGS and CAUTIONS is defined below.
CAUTION
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.
The units used throughout this manual conform to the SI international system of units of measurement.
1.2 Description
1.2.1 Bellows
Note: To install bellows safely, you must follow the guidelines given in Section 3.2.
Bellows are short, thin-walled components with deep convolutions. They are used to reduce the transfer of vibration
from a pump to a vacuum system.
1.2.2 Flexible pipelines
Note: To install flexible pipelines safely, you must follow the guidelines given in Section 3.3.
Flexible pipelines have a thicker wall section and shallower convolutions than bellows. Flexible pipelines provide a
convenient method of connecting vacuum system components and help to compensate for misalignment or small
movements in rigid vacuum pipelines. Flexible pipelines can be formed into relatively sharp bends and will hold their
position, as shown in Figure 1; minimum bend radii do not apply.
Flexible pipelines are intended for installation in static systems. They are not suitable for repeated flexing. This could
cause fatigue failure.
You must not use flexible pipelines on dry pump exhausts.
WARNING
Warnings are given where failure to observe the instruction could result in injury or death to
people.

1.2.3 Braided flexible pipelines
Note: To install braided flexible pipelines safely, you must follow the guidelines given in Section 3.4.
Braided flexible pipelines have an outer protective layer of woven stainless steel braid. They are suitable for use as
exhaust pipelines on Edwards dry pumps and other applications where there is significant gas pulsation or the
possibility of high gas pressures.
Braided flexible pipelines are intended for installation in static systems. They are not suitable for repeated flexing.
This could cause fatigue failure.

INSTALLATION
C105-11–880 Issue D
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.

4 STORAGE AND DISPOSAL
4.1 Storage
Store the components in cool dry conditions until required for use. When required, install the components as
described in Section 3.
4.2 Disposal
Dispose of the components in a safe manner in accordance with all local and national safety and environmental
requirements.
WARNING
Observe all appropriate safety precautions when you dispose of components which have been
contaminated with process substances or pump fluids.
