Piping Vibration Control Dynamic Studies, AIV, FIV, Pulsation

PIPING VIBRATION CONTROL DYNAMIC STUDIES – AIV – FIV - PULSATION Piping Reference Vibratec has a strong experience on vibrating process or utility pipes. Vibratec handles vibration issues at the design stage and also performs on-site control and troubleshooting. Context: Piping vibration can lead to severe damages on main lines & auxiliary systems (small bore, thermowell...): vibrations can induce cracks & leaks, leading to heavy maintenance and even installation shutdown. Proper understanding of the phenomena at stake is essential to prevent & / or mitigate these risks. Vibratec is a world-class expert that can help you keep your major piping vibration issues under control. A Combination of Multiple Factors Main types of piping vibration sources: • Process (e.g high-velocity fluids), • Organs (e.g valves, restricted orifices creating pressure drops) • Mechanical equipment (mechanical transmission of vibrations, pulsation inside the fluid). It is therefore of utmost importance to distinguish the main excitations in each piping vibration issue. Amplifying factors: Excitations can be amplified by improper design of the line & connected structure. Typical defaults are: •Supporting structure not stiff enough, •Mechanical resonance with the pipes and structure natural frequency, •Acoustic resonance in the line length, •Design of acoustic solution (restricted orifice, anti-pulsation bottles,…) inadapted to the system. Piping vibration issues are therefore not trivial and involve various disciplines (piping, structure, process). The intervention of an expert with a global approach is necessary most of the time. Thanks to its extensive experience and feedback from previous projects, Vibratec is the expert you need. Keywords: AIV: Acoustic-Induced Vibration, FIV: Flow-Induced Vibration.
