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.
