Noise and Vibration Attenuation
Mechanical room equipment frequently creates noise and vibration in a piping system, which can be difficult to contain. To isolate this vibration, designers can specify the use of Victaulic couplings.
In any application where undesired noise is being transferred through the piping system, owners and engineers who specify Victaulic grooved mechanical joining and receive two vitally important benefits:
1) significantly higher productivity
2) significantly reduced sound
Why do Victaulic couplings dampen noise and vibration?
The unique construction of the Victaulic grooved coupling enables the gasket to seal against pipe, while the ductile-iron housing provides both space for the elastomeric material to flex and containment to prevent overstretching. Victaulic couplings work to create a permanent leak-tight seal, with no need for additional reinforcement. Additionally, ductile iron has vibration-dampening qualities of its own, so the external housing also serves to absorb sound.
Is there proof Victaulic grooved couplings reduce pipe vibration?
Recently, Seattle-based SSA Acoustics LLP conducted field measurements and concluded that when placed in a formation of three couplings linked near to each other in close proximity to the source of vibration, Victaulic mechanical pipe systems deliver unsurpassed vibration isolation and sound attenuation characteristics. The use of additional Victaulic grooved couplings whether flexible couplings or rigid couplings, in the system will further reduce the transmission of vibration.
