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
