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 and manual production.
- Standard measures (length)
Advantages
- Easy installation
- Flanges are not in contact with medium, which enables lower grade material
- Galvanic surfaces / coatings possible
- Gaskets can be eliminated
- Additional movement capabilities
- Special measures (length, diameter, flanges) → custom made
- Different models (hose, reduction, multiple arches, filled arch, spool, …)
- Higher design pressure
- Special designs (spring rates, different inner and outer layers)
Materials
- Bellows: Various elastomers such as EPDM, EPDM Food Grade, Neoprene, Nitrile, Hypalon, Butyl, Viton
- Flanges: carbon steel and stainless steel.
- Other materials are available on request.
Standards and approvals
NDT and documentation: Can be provided per customer request e.g. Material Certificates and NDT test reports.
Recommended applications
- Air conditioning, heating and ventilating systems in industrial buildings and vessels
- Central and ancillary power generating stations in industrial buildings, factories, ships and offshore applications
- Sewage disposal and water treatment plant, pumps, etc.
- Process piping in pulp and paper plants
- Piping systems for chilled or hot water
- Cooling systems for power generation
- Feed water and draining lines for water works, sewage, sanitary piping systems etc.
