This two-day MasterClass provides a broad overview of analysis methods for defects in pipeline. The course begins with a summary of important material properties and a review of integrity assessment methods for pipeline defects. Analysis methods for corrosion are covered, including each of the methods cited in the most recent version of ASME B31G - Manual for Determining the Remaining Strength of Corroded Pipelines. A discussion on analysis methods for mechanical damage is also included.
Analysis methods for cracks are covered in the second day, which begins with a basic introduction to fracture mechanics. Attendees learn about the methods of measuring toughness associated with linearly elastic and elastic-plastic behavior. Next, the use of failure assessment diagrams and the development of the log-secant equation are discussed, followed by J-integral based assessments. Finally, both propagating fractures and fatigue are evaluated.
You Will Learn To:
- Identify which type of analysis tool is appropriate for common defect types
- Apply analysis tools, (such as ASME B31G and RSTRENG), for metal loss due to corrosion
- Describe the limitations of employing ASME B31G and RSTRENG
- Apply analysis methods for mechanical damage, and understand why they are less accurate than those for metal loss due to corrosion
- Explain the difference between flow stress and toughness related failures
- Identify when fracture-mechanics based analysis tools, such as the log-secant approach, must be used
- Describe how toughness affects the defect tolerance of a pipeline
- Explain how pressure cycling affects fatigue lives of crack-like defects
