Greg Quickel will present, “Pipeline Flaws 3/ Degradation” on March 17, 2022

This class has met the minimum and is continuing to take registrations.

Course Description

This 4.25 hour webinar is intended for those who need familiarization with the range of typical manufacturing flaws, fabrication flaws, and forms of in-service degradation found in pipelines.  Knowing the specific types of vulnerabilities can guide determination of where to inspect and what data to collect.  The presentation will be supplemented with other publicly available reference materials and a list of other related resource materials available from the respective publishers.

  1. An introduction to flaws and causes of pipeline failure. Do all flaws of the same size have the same effect on long-term integrity of the pipeline?
    Flaws vs. defects. The influence of service conditions on long-term flaw stability.
  2. Flaws resulting from contemporary and early vintage field welding and other field fabrication methods; API and ASME standards as references
  3. Going beyond measurement of thickness change: Identifying and characterizing degradation resulting from various in-service conditions (external corrosion, internal corrosion, mechanical damage from impact, damage from ground deformation, SCC, erosion)
  4. An introduction to historical and current API 5L requirements related to pipe dimensions, marking, and workmanship: when is an imperfection not a defect? Using the right benchmark for judging acceptability of imperfections.
