Best practice for the assessment of defects in pipelines – Corrosion

Corrosion is a common form of degradation in pipelines that reduces both the static and cyclic strength of a pipeline. In this paper, the best practices for the assessment of corrosion in pipelines are presented. Small scale and full scale tests, theoretical analyses and assessment methods are discussed and best practice in terms of assessment methods are described. The work stems from the results of a joint industry project, documenting the best techniques currently available for the assessment of pipeline defects (such as corrosion, dents, gouges, weld defects, etc.) in a simple and easy-to-use manual, and gives guidance on their use.
