Proc. ASME. IPC2022, Volume 1: Pipeline Safety Management Systems; Project Management, Design, Construction, and Environmental Issues; Strain-Based Design and Assessment; Risk and Reliability; Emerging Fuels and Greenhouse Gas Emissions, V001T07A019, September 26–30, 2022
Paper No: IPC2022-87211
... Abstract One challenge to pipeline operators is to identify potentially injurious dents among thousands of reported deformation features using limited information (e.g., reported dent’s length, width, and depth) and to prioritize the efforts and allocate the resources to obtain additional more...

Proc. ASME. IPC2022, Volume 2: Pipeline and Facilities Integrity, V002T03A028, September 26–30, 2022
Paper No: IPC2022-87098
... Abstract Dents are permanent plastic deformations of the pipeline that occur during pipeline construction and operations. Stress and strain concentration at dents may initiate cracks, which pose a threat to the integrity of the pipeline. Since formation of dents involves plastic deformation...

Proc. ASME. IPC2022, Volume 2: Pipeline and Facilities Integrity, V002T03A032, September 26–30, 2022
Paper No: IPC2022-87165
... Abstract Dents in pipelines, especially when associated with crack formation, pose a significant pipeline integrity threat. With crack formation during the initial indentation process, the fatigue life and failure pressure can dramatically reduce compared with crack-free dents. Over the past...

Paper No: IPC2022-87301
... Abstract Dents in buried pipelines either caused by third party mechanical damage or introduced during pipeline construction remain a leading contributor to reportable pipeline releases. API Recommended Practice 1183 (API RP 1183) provides a modern, shape-based fatigue life assessment...

Proc. ASME. IPC2022, Volume 2: Pipeline and Facilities Integrity, V002T03A040, September 26–30, 2022
Paper No: IPC2022-87360
... Abstract Mechanical damages such as dents are one of the most common threats to the structural integrity of buried pipelines traversing high population areas or mountainous terrains. Dents are defined as local inward depression in the pipe surface caused by external forces that produce pipe...
