Compressing system is one of the most important processes in hydrogen gas handling: production, storage, distribution until using. High pulsation waveforms produced during hydrogen compression can be reduced by employing snubber in the system. There are some pipes to flow hydrogen between two snubbers. An experiment has been conducted to investigate the features of pressure in the pipe placed between snubbers in reciprocating compression system. In measuring amplitude FFT was done and pressure RMS values at input and output of one the pipe using data for 10, 20, 30, 50 and 60 ㎐ motor frequency of compressor operation. The pressure pulsation reductions are varied from 16.415~35.151% and corresponding pressure losses 0.007~0.759%.
