Abstract: Regulation stations are used in a pipeline system to reduce the internal pressure in a controlled manner. When large flow rates and pressure drops are required, it is very important at the design stage to examine methods of minimizing the amount of noise and vibration created in a regulation run. Noise can easily be predicted with the sound power level (SPL) formula now available from most valve manufacturers. This should never be overlooked i n the selection of a control valve. If noise and vibration are to be minimized, two important criteria to consider are (1) the selection of the control valve, and (2) the configuration of the piping system entering and exiting the regulator settlng(s). Optimum design within these areas will limit the noise, the velocity and the turbulence in the gas stream. Before going further with the design considerations, lets take a closer look at noise and vibration.
