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
