Principles and Dangers of Resonance (By Wade Draper, WKC Group) The consequence? Potentially thousands of tonnes of product loss, occupational hazards and the emergency decommissioning of certain piping sections or in some cases entire facilities, resulting in substantial project cost coupled with significant losses in revenue – a production supervisor’s worst nightmare! The orchestra [...]

AIV Mitigation Considerations (By Ian Goble, WKC Group) The final step in an Acoustic Induced Vibration (AIV) assessment is the implementation of mitigation measures at locations with Likelihood of Failure (LOF) values of between 0.5 and 1, these mitigation measures can range from changes to process parameters, such as splitting the flow by adding [...]

Flow Induced Vibration – Diagnosis, Prognosis, Treatment (By Wade Draper, WKC Group) Introduction to Quantitative FIV Main Line Analysis Any structural system will exhibit a series of natural frequencies which depend on the distribution of mass and stiffness throughout the system. In the case of piping systems, this is influenced by: Each natural frequency [...]

Differences between AIV and FIV (by Richard Palmer, WKC Group) Every object/substance, has a natural frequency at which it is "willing" to vibrate. When an external agent applies a forced vibration that matches this natural frequency the object begins to vibrate, this is known as resonance. It is the energy in the fluid that [...]

Drilling down into piping fatigue: Acoustic and Flow Induced Vibration (by Richard Palmer, Service Lead at WKC) In industrial environments, failures of piping components can lead to unsafe operation, environmental damage, and a significant loss of revenue. Excessive piping vibrations are a major cause of machinery downtime, leaks, fatigue failures, high noise, [...]
