Abstract

Abstract

The calculation of pipe crack leakage rate is the key technology in leak-before-break (LBB) analysis. By comparing with the effective software and the experimental results, the domestic independently developed leakage rate calculation software PICLES is verified and studied. Compared with the international similar software (PICEP and SI-PICEP) with mature engineering applications, there is a small difference between PICLES and its calculation results. Compared with the experimental results of pipe crack leakage rate, the leakage rate calculated by PICLES is −80.23%~−43.79% different from that calculated by PICLES, and the leakage crack length calculated by PICLES is 21.84%~79.07% different from the measured crack length, which shows that the LBB analysis of supercooled water pipeline using PICLES is highly conservative. Therefore, PICLES can be used for LBB analysis in practical projects.
