Applications
For use in pressurized large sized pipe systems with
requirements for small reaction forces, providing
high reliability and long life. These expansion joints
are suitable for large extension in axial, lateral or
angular directions and they are used particularly in
cooling water systems at power plants, in condensers,
in gas and drinking water supply lines for pumps,
turbines and boilers. They compensate for thermal
elongation, correct misalignment, isolate vibrations,
dampen noise and absorb pressure surges.
Design
A custom manufactured rubber bellows with full-
face rubber anges.
Designed for working pressures 6-10 bar and
vacuum 0.8 to 1.0 bar as standard. Carbon steel
vacuum rings embedded within the rubber (never in
contact with the uid) are integral to the design.
Other working pressures and/or vacuum ratings on
request. Integrated painted steel anges as standard.
Build length 350/450 mm. Other lengths on
request.
