Merkmale

  • 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)

Vorteile

  • 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
