Characteristic Analysis of Leakage Sound Source of Steel Pipe and PE Pipe
[Purposes]The characteristics of leakage sound source of two kinds of gas pipelines,steel pipe and PE pipe,are analyzed.[Methods]The acoustic wave method was used to conduct sound source leakage experiments on PE pipes and steel pipes respectively through the gas pipeline leakage detection experimental platform.[Findings]The results show that the parameter characteristics at the leakage points of steel pipes and PE pipes increase with the increase of pipeline pressure under medium and low pressure conditions.When the pressure and aperture are constant,the time domain amplitude of steel pipe leakage is larger than that of PE pipe leakage.When the pressure and pore size are constant,the ASL and RMS values of steel pipes are higher than those of PE pipes.[Conclusions]The experimental results provide theoretical support for the leakage monitoring of urban gas pipelines,which is helpful to prevent pipeline leakage.
