Rubber expansion joints are universal expansion joints for axial, lateral and angular movement, available with fully developed rubber flanges and revolving steel flanges.

The single convolution bellow is made from different rubber qualities with pressure carrying reinforcing high tensile nylon cord or as an alternative with reinforced layers Kevlar- or fibreglass.

Fields of application for rubber bellows
For use in pressurised 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 thermal elongation, correct misalignment, isolate vibrations, dampen noise and absorb pressure surges.
