燃气管道泄漏检测与定位方法探讨

摘要

Pipeline is the main method of natural gas transportation. However, gas pipeline leak occurrs frequently due to corrosion, third-party damage and so on, not only affecting the normal transmission of gas, but can also causing environmental pollution, fire, explosion and posing a great threat to people＇s lives and property safety. So gas pipeline leak detection and location technology has great practical significance and broad application prospects. The current domestic and international methods of leak detection and location are introduced in this paper. And the advantages and disadvantages of various detection methods are pointed out and their application conditions are analyzed.%管道运输是天然气的主要输送方式，然而由于腐蚀、第三方破坏等原因导致的燃气管道泄漏事故时有发生，不仅造成自然资源的浪费、环境的污染，而且也影响正常的生产和生活，危害人类的身心健康，造成人类生命财产的巨大损失。因此，如何根据燃气管道运行信号，及时发现燃气管道泄漏并准确判断管道泄漏位置就具有重大的现实意义和广阔的应用前景。本文主要介绍了目前国内外燃气管道泄漏检测与定位方法的性能指标，指出了各种检测方法的优缺点及适用条件。
