Bill Amend will present a live webinar, ” Introduction to Pipeline Steels: Metallurgy, Manufacturing, and Standards” on October 17, 18, 2022
Bill Amend, P.E. instructing
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. Examples include, but are not limited to:
- When is API 5L PSL 1 pipe “good enough” and when is the superior 5L PSL 2 pipe NOT “good enough” without supplemental requirements?
- When is toughness important and how much do you need?
- Why won’t a welding procedure qualification test plus UT or radiography tell you everything you need to know about your production welds?
- Is there a downside to a really low carbon equivalent (Pcm) value?
- Can I avoid a lot of pipe issues by using seamless pipe?
- What pipe and fittings are most likely to be the most susceptible to weld cracking, and why?
- Is a pre-1970 vs. post-1970 manufacturing date the best way to predict “good” v. “bad” ERW characteristics?
- How do ASTM grades compare to similar API grades?
- Why does my third-party lab tensile test not agree with the MTR?
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.
- What Characteristics are Important in Pipeline Steel and How are They Measured?
- Strength (YS and UTS)
- Toughness (static and dynamic testing)
- How is Pipeline Steel Made?
- Ingot casting v. continuous casting to produce skelp
- Influence of processing (example: rolling and forming, heat treatment, cold expansion)
- How are Pipe and Fittings Made?
- Seamless pipe
- Seamed pipe
- Fittings and bends
- Typical flaws and vulnerabilities
- An introduction to other alloys in pipeline systems (stainless steels, cast irons, nickel alloys, wrought iron)
- What Happens When We Weld Pipeline Steel?
- Weld metal/welding process selection
- Changes in the heat affected zone: strength, toughness, corrosion susceptibility
- What Codes and Standards Address Pipeline Steel and Pipe/Fitting Manufacturing?
- How Have Pipe Manufacturing and Fabrication Practices Changed Over Time and What Does That Mean for Pipeline Integrity?
