Movement compensation and construction
Rubber expansion joints for industrial piping systems
Rubber expansion joints are used within industrial piping systems for absorbing movements, vibrations and stresses caused by thermal influences and mechanical loads.
Due to their flexible properties, rubber expansion joints contribute to protecting piping systems and connected equipment against damage and stresses within the installation.
Protection against vibrations and stresses
Rubber expansion joints compensate for axial, lateral and angular movements within piping systems.
In addition, they are used for absorbing vibrations originating from machines, pumps, compressors and other installations.
Stresses and misalignments occurring during installation can also be absorbed.
Different materials and versions
Depending on the application, rubber expansion joints are available in different materials, including:
- EPDM
- Neoprene
- Nitrile
- Hypalon®
- PTFE
- Viton®
- Butyl
In addition, different versions are possible with, among others, flanges, couplings, tie rods and PTFE lining.
Process conditions and application areas
Suitable for a wide range of media and process conditions
Rubber expansion joints are suitable for applications involving a wide range of liquids and gases.
Depending on the material selection, solutions can be tailored to temperature, pressure and media resistance within the process.
In addition, the expansion joints feature high resistance to overpressure and shock loads.
Applications within industry and utilities
Rubber expansion joints are used within a wide range of industrial and utility applications, including:
- Air conditioning systems
- Cooling water and condensate pipelines
- Heating systems
- Chemical installations
- Marine applications
- Pump connections
Compact and flexible solutions
Rubber expansion joints are characterised by their compact construction, flexibility and relatively low weight.
This makes them suitable for applications where movement absorption and vibration damping are important within limited installation spaces.
