Rubber expansion joints are used in heating, ventilation and air conditioning systems, power plants, refineries, chemical plants, shipbuilding and many other industries. Beyond high extensibility they are characterized by a high movement absorption and excellent noise reduction. According to the expansion joints application there are different kinds of rubber. Fabrics of synthetic fibers are used as the pressure medium. Flanged connections are self-sealing.

Features
Transportation or piping systems that carry fluids, slurries or gasses under pressure or vacuum at varying temperatures.
Reduction of vibration.
Dampen sound transmission.
Compensate movements due thermal changes, misalignments caused by wear, load stresses, settling of supporting foundations.
Molding production with long radius arch.
Standard measures (length).
Advantages
Easy installation, flanges can be rotated.
For installation with “torsional misalignments”.
Flanges are not in contact with medium, which enables lower grade material.
Galvanic surfaces/ coatings possible.
Gaskets can be eliminated.
Additional movement capabilities.
Self cleaning arch (no need filler material).
Economic.
