In the process of com pressor operation, p ipeline vibration occurred frequently, so it has a strong mi pact on safety pro duction. It is very necessary to research the causes and the correspond ing elmi inates vibration m ethods. Th is paper firstly analyzed threem ain causes of compressor pipeline vibration and correspond ing elmi ination vibration m ethods. Then com puting form ula for p ipeline press heterogeneous degree, gas colum n s natural frequency, reso nance tube length and p ipeline s natural frequency w as given. Finally, them ethods of causing pipeline vibration w ere put forw ard and them ethod of indentify ing pipeline vibration cause is obtained.
