摘　　要：关于埋地油气管道腐蚀研究一直都是油气储运及集输工程的一个重要课题。阐述埋地油气输送管道腐蚀的主要形式及机理。在输油管道的内腐蚀、杂散电流干扰、应力腐蚀开裂、涂层失效等方面进行了分析,探讨高强度管道钢腐蚀中最突出的问题。The corrosion of buried oil and gas pipeline has always been a problem for oil and gas storage and transportation and oil-gas gathering.In this paper,main corrosion forms of buried pipelines and main the corrosion mechanism are analyzed.Then effects of internal corrosion,the disturb of stray current,stress corrosion cracking,coat failure are analyzed.And it discusses the most serious problems in widely used high-grade pipeline steel.

关 键 词：腐蚀 内腐蚀 杂散电流 应力腐蚀开裂 高强管道钢
