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.
Our pulsation studies cover acoustical and mechanical aspects according to API 618 DA3.
DRG conducts pulsation studies according to API 674 or for metering pumps according to API 675
Design and sizing of pulsation dampeners for reciprocating pumps and compressors.
AIV, Acoustically Induced Vibrations
Acoustical fatigue can occur due to acoustical noise downstream of valves.
How does a system respond to a shaking force.
Flow Induced Turbulence
Broadband kinetic energy is generated by abrupt flow changes in bends and tees.
Field measurements identify whether remedial action is required.
Determine if fatigue failure could occur due to vibrations in the piping.
Vibrations may arise due to vortices shed from dead-leg branches and protruding probes.
