Fracture propagation and arrest in high-pressure gas pipelines: an overview of this Special Issue
Dash Weeks, Su Xu, William Tyson
ARREST OF FAST DUCTILE fractures in gas pipelines is critical for safety and environmental protection and is an active R&D area. In order economically to design gas pipelines and select materials, a suitable method to predict arrest toughness, and the availability of test methods to measure this toughness, are vital to pipe manufacturers, pipeline operators, and regulators. This has become a pressing issue, as many new pipelines will operate in challenging environments (for example remote, Arctic, and offshore), and will be designed for stringent conditions (high operating pressures with large-diameter, thick-wall, high-strength steel pipe). The intent of this Special Issue is to survey the state-of-the-art in the development of methods to arrest fast ductile fractures in gas pipelines.
