Piping vibrations | Flow induced & acoustic induced ...

Piping vibrations. Vibration of process plant piping can be a significant risk to asset integrity and safety. This is often due to flow induced vibration (FIV) and acoustic induced vibration (AIV), and is related to the flow of the main process fluid through the piping system.. Other possible sources of piping vibration include:. Mechanical vibration and pulsations from compressors and pumps;
