【摘要】 长输管线泄漏检测技术是管道输送业正常、高效运行的保证,由于气体具有可压缩性、摩阻小、管输压力高、流速快等特点,致使气体长输管线的泄漏检测技术相对液体管线难度要大一些。本文首先介绍几种适合于气体管线的泄漏检测技术及其工作原理,然后结合我国气体长输管线的实际情况,提出了实际实施过程中应该注意的若干问题及相应对策。更多还原

【Abstract】 Leak detection technology plays an important role for the long gas-pipeline to run normally and efficiently. Due to the compressibility and low friction and high pressure,it is more difficult to detect the leakage of the gas than that of liquid. This thesis introduces several leak detection technologies for gas and mainly focus on the detecting principle and measurement technology. It also provides some strategies according to the real suitua-tions of our country.更多还原
