Analysis of Pressure-Changed Effect on Leakage in Pressure Decay Leak Detection

Abstract:

Article Preview

The method of pressure decay leak detection measures leakage by detecting interior pressure change of tested tank. As pressure change of tested tank affects leak rate, there is a certain deviation between tested leakage and actual leakage under constant pressure. Currently, all of the international leakage standards are developed under constant pressure conditions, therefore, this leakage deviation is mainly concerned in leak detection. In this paper, a deviation calculated model between tested leakage and actual leakage under constant pressure was developed. And the experimental results showed a good agreement with the model simulation date.
