Abstract

In order to research the relationship between the change of bolt strain and the acceleration of pipe flange, in this paper, the vibration experiment platform which was a floating bolt flange pipe system under different bolt pre-tightening force was built. Experimental results show a high correlation between bolt strain and acceleration, and also show that the change of pipe acceleration can indirectly characterize the change of the flange sealing performance, which can provided the certain basis for online monitoring the sealing performance under certain special environments. Besides experimental results also indicate that the increase of pre-tightening force can improve the sealing performance of flange bolts in the case of vibration.
