Burst Pressures of Pipes Containing Dents and Gouges

Mechanical damage to pipelines may take the form of dents and gouges, which may also incorporate cracks. The combination of a gouge within a dent has long been recognized as the most severe form of damage, and can result in failure at very low internal pressures. Yet despite much expensive full-scale testing, predictions of subsequent burst pressures of such damaged pipes are unreliable, and assessment procedures are very conservative. This...
