Flexible coupling

  1. A flexible coupling accommodates pipe deflection and non-alignment as below: if nominal diameter < DN200, deflection angle is>=1degree;If nominal diameter>=DN200, deflection angle is>=0.5degree but <1degree
  2. The C-shaped rubber gasket provides excellent self-sealing capabilities in both low and high pressure service as well as under certain vacuum conditions
  3. The design and construction of the coupling with elastomeric gaskets can provide significant noise and vibration absorption as well as seismic stress.
  4. With the removal of just a few bolts you can easily access the system for cleaning、maintenance、changes or system expansion.
  5. Coupling is non-directive and pie can be rotated 360 degree during installation.
  6. Coupling keys engage the full circumference of the grooves and provide significant pressure and end load restraint against pipe movement from internal and external forces.
  7. The pipeline is allowed to have axial expansion and contraction and angular displacement, which is suitable for hot water pipelines, air-conditioning water pipelines, and outdoor outdoor pipes.
