Single Grooved Nodular Cast Iron Quick Coupling

Product introduction:

The flexible coupling for use in a variety of general piping applications of moderate pressure services.

The coupling features flexibility that can deal with misalignment,distortion,thermal stress,vibration and noise and also resist seismic tremors.

Grooved couplings are subjected to internal pressures and exterior bending forces during service.

ASTM F1476- 07 defines a coupling as a joint where there is essentially no available free angular or axial pipe movement and a flexible coupling as a joint wherein there is available

limited angular and axial pipe movement.

•Standard flexible coupling provides flexible connection by the gap between pipe groove and coupling key.

•Unique design allows both axial and radial movement,suitable for pipeline with flexibility under intermediate pressure.

•Enhanced body resists 4 times working pressure.

Product Feature And Application:

  • Housing material:Ductile iron conforming to ASTM A-536,grade 65-45-12

  • FM Approved & UL Listed:R.W.P. rated working pressure 300PSI(2.065 Mpa/20.65 bars)

  • Housing Finish:Fusion Bonded Epoxy Coated(Optional:Hot Deep Galvanized and Others)

  • Coupling gasket material:EPDM(Optional:Nitrile NBR,Silicone and others)
