摘　　要：城市埋地燃气管道泄漏会带来巨大影响。对城市埋地燃气管道泄漏的原因进行了分析,阐述了造成城市埋地燃气管道防腐层破损导致泄漏的人为因素和自然因素,介绍了城市埋地燃气管道外防腐层检测和各种常用壁厚检测技术的优缺点。Leakage of buried gas pipelines in cities could have a huge impact.The reasons for the leakage of urban buried gas pipelines were analyzed,and the human and natural factors that caused the damage of the anticorrosion layer of urban buried gas pipelines to lead to leakage were elaborated.The advantages and disadvantages of external anti-corrosion layer detection and various commonly used wall thickness detection technologies for urban buried gas pipelines were introduced.
