ENGINEERED SYSTEMS

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 flexible. Able to compensate for high movements due to its low inherent resistance.

Steel backing flanges with supporting collar to ensure the smooth movement of the bellow.
