Managing Cracks and Seam Weld Anomalies on Pipelines
November 18-19, 2014
Various forms of cracks or crack-like indications are known to be present on pipelines, which could become a safety concern to their safe operation. The most typical forms of cracking and its derivatives are environment-, manufacturing- or operations-related, such as stress corrosion cracking, corrosion fatigue cracking, hydrogen-induced cracking, hook cracking, and seam-weld anomalies (such as those related to 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 anomalies 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.
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 on 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 action.
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).
Sergio Limón has worked in the oil & gas pipeline industry for more than 15 years with emphasis on pipeline integrity threat analysis and response. He was employed for 10 years with a large owner and operator of natural gas gathering, processing and transportation services. He led for six years the Asset Integrity group for the western division responsible for the analysis, response and remediation of integrity threats as well as the implementation of the Gas Integrity Management Program. Sergio holds B Sc. and M Sc. degrees in Mechanical Engineering with emphasis in fracture mechanics and materials from the University of Utah. He is the founder of LIMON Pipeline Analytics.
