摘　　要：针对国内某LNG装置出现的管道振动问题,发现该装置管道振动存在区域性、多发性、后发性、振动区域动能大、振动区域远离传统振源等特点,利用英国HSE EI指南的方法原理结合装置管道振动的特点,将振源锁定在因不均匀沉降引起的支架托空从而引发的流激湍动,成功解决该装置管道振动问题。通过该案例,为LNG装置管道的设计、现场管道振动问题的处理提供参考和建议。In view of the pipeline vibration problem of a certain domestic LNG plant,it is found that the pipeline vibration of the plant is regional,multiple and posterior;there is large kinetic energy in the vibration area and the vibration area is far away from the traditional vibration source.Using the methods and principles of the British HSE EI Guide and combining with the characteristics of the pipeline vibration of the plant,the vibration source is locked in the fluid-induced turbulence caused by the support lifting,resulting from uneven settlement.Then the problem of pipeline vibration of the plant is solved successfully.This case study provides reference and suggestions for the design of LNG plant pipeline and the treatment of on-site pipeline vibration problems.
