• 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
