Materials
Applications
For cooling water systems at power plants, in gas
and drinking-water supply lines, at condensers, for
pumps, turbines and boilers for the absorption of
movements, oscillations, noises and vibrations.
These expansion joints are suitable for large
extensions in axial, lateral or angular directions.
They are suitable in pressurised large-sized pipe
systems with requirements for small reaction forces,
providing high reliability and long life.
Design
Rubber bellow with high convolution and therefore
highly exible. Able to compensate for high
movements due to its low inherent resistance.
Steel backing anges with supporting collar to
ensure the smooth movement of the bellow.
Note: Other materials available. Please ask.
