Course overview
This webinar, split into two sessions presented over two days, covers the basics of pipeline steel metallurgy with emphasis on directly addressing frequently asked questions and common misconceptions about steel pipe and fittings. 

The webinar starts with a description of how pipelines fail since the failure modes influence what metallurgical measures are taken to minimize susceptibility to those failures. The major types of pipe and fitting manufacturing processes, and common flaws associated with them will be reviewed, including discussion of obsolete types of pipe that are still in service, for example, pipes with lap seams, furnace butt weld seams, and flash weld seams. The review will include a brief summary of some historical field construction practices that influence the integrity characteristics of those pipelines that are still in service.

Attendees will learn the significance of yield strength, ultimate tensile strength, hardness, toughness, and composition and how those attributes are specified and measured, including how test procedures can influence results. Attendees will also be introduced to the topic of pipeline welding since welding can introduce new flaws and can have a significant impact on pipe properties and susceptibility to various forms of in-service degradation.

This webinar will also introduce attendees to how various manufacturing, standards, and specifications compare to each other, how they have evolved over time and how they influence pipe mechanical properties, weldability, and long-term integrity.

Start Time: 9:00 a.m. (CDT)
End Time: 1:30 p.m. (CDT)
