Method to Establish Sound and Acceleration Levels of High Pressure Reducing Valves

Abstract Severe service control valves or better, high-pressure reducing can see inlet pressures in excess of 4000 psi. Such are found industries ranging from gas petroleum wells, to chemical plants and steam-producing power (Goodwin, “Specifying Control Valves for Service Conditions”, INTECH FOCUS, November (2022), p. 20). convert high levels kinetic energy through a process conversion sound-producing turbulence reduced pressure level. Less desired by-products such as sound that exceed 120 decibels, is comparable standing next jet plane taking off. Part this manifests itself mechanical vibration which cause undesirable pipe acceleration which, over time, could severely damage piping (Almasi. “Flow Induced Vibrations Piping Systems”. P.I. PROCESS INSTRUMENTATION, July, 2020; Blake, 1986, “Mechanics Flow Sound Vibrato,” Vol. II, Complex Flow-Structure Interactions, Academic Press, Orlando, FL). Proposed here an easy computer programmable method check the associated with noisy valves. It believed paper harmonizing all aspects aerodynamic valve noise, pressure, power, vibration, be value. The purpose explain how estimated. There four steps involved: (1) calculate level (SPL) given data, (2) into (Lwi), (3) find maximum internal peak frequency (fp). (4) Based on sound, (in m/second2).
