Online Tool to Determine the Likelihood of Failure (LOF) due to Acoustic Induced Vibration (AIV) at a Discontinuity

The below online tool allows for the Likelihood of Failure (LOF) due to Acoustic Induced Vibration (AIV) to be calculated at a particular discontinuity. The user must know the outside diameter and wall thickness of the mainline pipe, the outside diameter of the branch connection and the sound power level (PWL) at the point to be assessed. The LOF at that point will then be calculated and based on the result mitigation may be required at that discontinuity. The calculations used in this tool are based on those shown in the Energy Institute’s ‘Guidelines for the Avoidance of Vibration Induced Fatigue Failure in Process Pipework’ 2nd Edition.
