Internal corrosion is one of the most common reasons resulting in oil/gas pipeline failures. Statistics showed that 54% of Albertan pipeline failures were attributed to internal corrosion in 2002. In particular, internal pitting corrosion is a predominant failure mechanism of pipelines. Owing to the inherent difficulty to detect and design against, the pitting process is extremely insidious. It is mandatory for pipeline operators to avoid these localized failures as they potentially cause major disruptions to many parties and stakeholders.

内腐蚀是导致油气管道失效的最常见原因之一。统计数据显示，2002年艾伯塔省54%的管道故障归因于内部腐蚀。特别是，内部点蚀是管道的主要失效机制。由于检测和设计的固有困难，点蚀过程是极其隐蔽的。管道运营商必须避免这些局部故障，因为它们可能会对许多方和利益相关者造成重大干扰。
