This paper describes a direct method for studying vibration of piping systems for reciprocating compressors, based on the requirements given by API-618 Design Approach-3. The reliability of this direct method is examined by some experiments with a test piping system using pressure pulsation and nodal vibration measurements. Overall pressure pulsation amplitude and its frequency components at each measurement point agree well with the results from numerical analysis. Close evaluation of "pipe-support' stiffness" and boundary conditions are necessary to perform dynamic analysis of the piping system in relation to the pressure pulsation generated by the reciprocating compressor; they affect the accuracy of the final estimation of nodal displacement distribution of the piping system.
