Excessive pipe vibration lead to critical loads. Here, vibration analysis can ensure the identification and elimination of bad excitation mechanisms.

By measuring the vibration acceleration, vibration speed or vibration displacement it can be verified whether the vibration level of piping and, if applicable, of connected pumps and aggregates lies within acceptable limits, thus providing for an adequate bearing load, i.e., fatigue strength.

But even if too high pipe vibration has been found, performing multi-channel vibration analysis is recommendable, since knowledge of the excitation mechanisms is needed in order to be able to effectively reduce the vibration. Here, unlike the simple, hand-held vibrometer measurements, multi-channel measurements enables modal as well as frequency selective analysis.

Typical is, for example, vibration that is caused by turbulent flow and has the natural frequency (resonance frequency) of the piping. Such vibration, having the piping’s natural frequency, can cause even due to slightest excitation large deviation. Pipe vibration can also be enforced by pumps, compressors, or fluid resonance. As a result, vibration-induced cracks or leakages can occur. This creates an operational risk for technical equipment and can lead to production disturbances and consequential damage
