摘要: 

随着城镇基础设施的大规模建设,地下金属构件数量及材质类型增多,埋地燃气管道服役环境日益复杂,尤其小区内埋地燃气管道腐蚀泄漏事故频繁发生,但目前对于小区内埋地燃气管道泄漏原因缺乏系统的分析。本文以某小区内高频泄漏燃气管段为研究对象,通过现场测试与试验分析明确了该管段高频泄漏的原因,并提出了解决方案,可为国内同类案例提供参考。

关键词 燃气管道高频泄漏现场试验泄漏原因    
Abstract

With the large-scale construction of urban infrastructure, the number and material types of underground metal components have increased, and the service environment of buried gas pipelines has become increasingly complex. In particular, corrosion accidents of buried gas pipelines in residential areas have occurred frequently, however there is a lack of systematic analysis for the ground gas pipeline leakages. In this paper, the high-frequency leakage gas pipe section of frequent leakages in a certain district is taken as the research object, where a practical on-site inspection and laboratory test were performed so that to clarify the relevant case history and finally several countermeasures are proposed, which is believed to be proper reference for similar cases in the country.
