Pulsations and Vibrations

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.
