摘要
腐蚀是影响石油天然气管道可靠性和使用寿命的关键因素之一。近年来,石油天然气集输和长输管道建设发展迅速,输送介质成分复杂、腐蚀性强,致使管道腐蚀问题日益突出。针对石油天然气长输管道和集输管道内腐蚀和外腐蚀的特点,总结了相关腐蚀防护技术,并介绍了腐蚀防护检测监测技术的研究进展及应用现状。
Corrosion is one of the key factors to impact on petroleum and natural gas pipeline reliability and the service life. Recently, oil and natural gas gathering and transportation pipeline construction is being developed rapidly. However, the conveying medium has complex composition and strong corrosion, which result in that the pipeline corrosion becoming increasingly prominent. In this paper, the related corrosion protection technology with respect to the petroleum and natural gas pipeline, internal corrosion and outer corrosion characteristics were summarized, and the corrosion protection detection and monitoring technology research progress and application status were introduced.
