CouplingsFlexible Coupling Systems and Performance §Standard flexible grooved-type couplings allow controlledangular, linear and rotational movement at each jointto accommodate expansion/contraction (see note below),settling, vibration, noise and other piping system movement.These features provide advantages in designingpiping systems but must be considered when determininghanger and support spacing and location.Victaulic couplings offer superior vibration attenuationcharacteristics to both flexible metal and elastomericflexible arch-type connectors.Independent vibration testing data (request publication26.04) verifies that three Victaulic couplings in closeproximity to a vibration source (pump, equipment, etc.)provide superior vibration attenuation in piping systems.Both flexible and rigid couplings offer reduced constructionschedules, plus the convenience of a union at everyjoint and the proven pressure-responsive “C” shapedVictaulic gasket. Both type products fit into standardroll or cut grooved pipe and provide the security of fullcircumferential engagement of the coupling housing intothe groove for high pressure and end load service.SECTION 1: COUPLINGSNominalSizemmInchesSizeActualOutside DiametermmInchesAllow.
