Abstract: Excessive sound power, which may be caused by the flow of gas through a high pressure drop device such as a valve or orifice plate, can excite pipe shell modes. Valves and orifice plates are not the only elements that can cause excessive sound, but they are the most prominent high pressure drop devices that need to be addressed. This mechanism of excitation can lead to failures and is called Acoustic Induced Vibration (AIV) and flow Induced Vibration (FIV) The configuration of the discharge piping and velocity of the discharge gas in the piping have a direct effect on whether acoustic vibrations may cause fatigue failure of the discharge piping. This study explains the calculations and criteria to be used in calculating and evaluating potential for Acoustically Induced Vibrations (AIV) and flow Induced Vibration (FIV) in piping systems. This paper also covers the screening and detail methods for determining if a piping system is at risk from AIV and FIV. This procedure requires. Mitigate the risk from AIV and FIV Bring to the attention of all systems that were determined to be at risk from AIV and FIV Identify the methods employed to mitigate the risk of AIV and FIV
