Managing Cracks and Seam Weld Anomalies on Pipelines
November 4-6, 2015
|Day 1 & 2:||8am-5pm|
Various forms of cracks or crack-like indications are known to be present in pipelines, which could become a safety concern to their safe operation. The most common forms of cracking are manufacturing related, environmentally induced, and mechanically driven, such as Stress Corrosion Cracking, Corrosion Fatigue Cracking, Hydrogen-Induced Cracking, Hook Cracks, and anomalies associated with the Seam Weld (as those found in vintage ERW/flash-welded pipe).
This course will provide an integrated, data-driven approach for addressing these forms of cracking and seam-weld anomalies. It covers in greater depth the formation of these types of features and the conditions that drive their growth until they become unstable, leading to leaks or ruptures. The appropriate assessment methods such as ILI crack tools, pressure testing and direct assessments will be presented as well as traditional and current engineering approaches for establishing crack severity and determining future integrity. Case studies will be reviewed and discussed throughout course instruction. Appropriate repairs options for cracks will also be covered.
This course will be taught at the Pipeline Research Council International (PRCI) Technology Development Center in Houston Texas. Throughout the course, the instructor will be using pipe samples with actual cracks and seam weld anomalies located at this research center. Attendees will benefit from experiencing a world-class collection of pipe samples and discussing how the various types of cracks form and grow in pipelines.
On completion of the course, the student will understand what factors contribute to the formation and growth of crack‐like features and seam-weld anomalies in pipelines. In addition, the participant will be able to gather and analyze the type and extent of cracking found, key operational parameters, pipe material properties, full-scale testing data, and ILI crack tool data, and to apply industry-recognized engineering methods for developing and recommending appropriate remedial actions.
Participants will receive a full set of course slides and notes in paper and electronic form, in color throughout.
Upon completion of the course, participants will be eligible to receive 1.6 Continuing Education Units (CEUs).
