Development of a mechanistic model and predictive methodology for internal pitting corrosion of pipelines in oil/gas production

点击翻译按钮获取中文摘要

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.
