Greg Quickel and David Norfleet with DNV present “Introduction to Pipeline Steels: Metallurgy, Manufacturing, Standards, and Specifications” as a webinar on October 27, 2021.

Maybe you think this class is not necessary. Maybe you think that as long as the pipe meets API 5L, that is good enough, and no further understanding is needed. Maybe you think an understanding of metallurgy is just for the materials engineers. Maybe you already know that a low carbon equivalent is preferred for welding; therefore, a very low carbon equivalent is always best, right? Maybe you think stress relief considerations for a quenched and tempered fitting can be the same as for a normalized fitting.  Maybe you “know” that seamless pipe is preferred for compressor and pump station applications because that way, there is no seam to fail from fatigue.  Maybe you “know” that X70 is more difficult to weld than X52 because it is harder and stronger.  Maybe you “know” that Lab “A” is wrong because their tensile test results are different from those of Lab “B”.  This webinar will show you that you are wrong.  Or maybe you want some clarification of the difference between hardness, toughness, and ductility and want a better understanding of how they are measured and how they are influenced by steel manufacturing.  And, what is the big deal with “hard spots” or LF ERW?  If you do testing on a couple of randomly selected pipe joints, will the results be representative of the entire pipeline segment? Join in and find out.

Join in and find out.

This webinar will introduce attendees to the topic of pipeline metallurgy and how manufacturing, standards, and specifications influence pipeline mechanical properties, weldability, and long-term integrity.  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.  The review will include a brief summary of some historical practices that influence current pipeline characteristics.  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 have a significant impact on pipe properties and susceptibility to various forms of in-service degradation.
