Rubber expansion joints have a wide range of different applications – they are used in domestic heating systems, air conditioning and ventilation systems as well as in plant construction, mechanical engineering, shipbuilding, chemical plants and power station construction. In addition to absorbing movements in an axial, lateral or angular direction, they are also used to damp noise in piping systems. Depending on the application, rubber expansion joints are available in various rubber qualities and with or without external reinforcement. The rubber expansion joints are standardly equipped with flanges in accordance with EN 1092-1 PN 10/16 – other flange designs are available on request.
