Introduction to pipeline flow-induced vibration

to minimize the risk of pipe vibration and to improve safety, reliability and efficiency of process and production operations. Through engineering simulation, we may be able to meet these aims while reducing conservatism and cost. Flow-induced vibration of pipelines and piping can be caused by a number of mechanisms including:

Pulsations and Vibrations Engineering

The varying flow caused by reciprocating pumps, compressors or process conditions leads to a pulsating flow within the connected piping. Excessive pulsation amplitudes can lead to mechanical vibrations and thereby fatigue failure of the piping or supporting. To avoid these problems good system design is key and here DRG can be your perfect partner.
