Vibration assessment is our on-site service to document existing vibration and/or natural frequencies for the purpose of providing information to the client regarding vibration severity as well as to document the benefit to using ZetaQuest Technologies, LLC vibration damping hardware.

This is a common service for piping vibration issues where we come on site to document the current vibration levels on specified piping and compare to known standards/guidelines to evaluate the vibration severity as compared to generally accepted limits.  The review will provide evidence to support client’s risk review for the installation.  We can also guide on-site personnel (or others) to complete the measurements for us if on-site work is restricted.

The information gathered is then used to assess the benefits of using either our Rohr or Starr line of dampers.  The Rohr line is intended for vibration on piping from about 10 Hz and higher, while the Starr line is applicable for low frequency swaying up to about 60 Hz.  Each line has benefits that will be reviewed for each application.

The ideal goal would be to achieve damping of 10% or higher on problem lines for excitable modes, although damping levels as low as 2-3% may be adequate to mitigate elevated vibration to acceptable limits.

The deliverable from the Vibration Assessment service is a written report describing the scope of review, field measurements, comparison to known standards, and a description of the ZetaQuest hardware that is applicable for mitigating elevated vibration.  It is likely that a proposal for ZetaQuest hardware will be delivered with the report.
