架空低压燃气管道裂缝泄漏量计算与实验测试

Calculation and Experimental Test of Leakage at Crack of Overhead Low-pressure Gas Pipeline

架空低压燃气管道裂缝产生燃气泄漏,其泄漏量用仪器难以测量。模拟管道泄漏工况,在实验室获取计算公式中的管道裂缝流量修正系数,可测算架空管道裂缝燃气泄漏量。阐述了架空低压燃气管道裂缝泄漏量的计算原理、裂缝流量修正系数测试流程、实验结果。

It is difficult to measure the gas leakage at cracks of overhead low-pressure gas pipeline by instrument. By simulating the working condition of pipeline leak, the correction coefficient of pipeline crack flow rate in the calculation formula obtained in the laboratory can calculate the leakage at cracks of o- verhead low-pressure principle of leakage at gas pipeline, the test of crack flow rate and pounded. gas pipeline. The calculation cracks of overhead low-pressure process of correction coefficient the experimental results are expounded.
