油气管道腐蚀检测评价技术及应用

Corrosion detection and evaluation for oil and gas pipelines

本文系统阐述了油气管道的内外腐蚀检测技术。对某油田油气管道站场内的架空管道开展了常规检测及新技术的综合检测评价。对于埋地管道,分别从腐蚀环境、腐蚀防护系统非开挖检测、开挖直接检测进行外部腐蚀评价。依据输送介质、工况及管道分布进行流场分析及开挖直接检测对内腐蚀危害进行评价。

This paper describes the corrosion detection used for the internal and external oil and gas pipeline. The comprehensive evaluation on the routine inspection and the new technologies of the aerial pipelines in the station of one oilfield are carried out. The external corrosion of the buried pipelines is evaluated with respect to the corrosion environment,non excavation detection,and direct detection evaluation. The internal corrosion is detected based on flow field analysis of the conveying medium,working condition and pipeline distribution as well as direct detection.
