Abstract：

In the process of gas production, pressure reducing devices in gas phase pipe may produce noise in case of pressure drop and large fluid flow rate, large noise may cause pipe vibration and strong acoustic vibration can induce fatigue cracking of the pipe and can potentially cause catastrophic pipe failure. In engineering design phase of pipe system, analysis on acoustically induced vibration pipes can effectively decrease risk of pipe fatigue failure resulting from such vibration. Overseas studies on acoustically induced vibration pipes begin early and analysis on acoustically induced vibration pipes is required in design phase of large overseas projects. However, little similar reports can be found in China and there are no relative requirements for analysis on acoustically induced vibration pipes even in very large projects. Based on research literatures and engineering practices and in combination with engineering examples in natural gas treatment, proposed are preliminary screening methods and steps of acoustically induced vibration pipes in design phase so as to pay attention to analysis on acoustically induced vibration pipes and provide some preliminary engineering experience for engineers and especially, preliminary screening of acoustically induced vibration pipes can lay foundation for detailed analysis on acoustically induced vibration pipes.
