Multiple excitation sources exist within modern process plants that can cause damage due to vibration related degradation mechanisms. Without identification and control, these can lead to component failure and the associated safety, environmental, business and reputational losses.
One such issue is acoustically induced vibration (AIV) choked gas flow through pressure reduction devices which can generate high levels of acoustic energy. This can excite the higher frequency pipe shell modes of the downstream piping and potentially lead to excessive cyclic stress at discontinuities such as small bore connections and pipe supports.
