7.30: Registration, breakfast, coffee
8.00 – 5.00: Course
It will be necessary to bring a laptop to this course.


Participants of this course will be introduced to the theory and implementation of state-of-the-art nondestructive testing methods to verify material properties, not only for compliance with regulatory requirements but also for better informing their integrity management programs. Attendees will learn about benchmark laboratory destructive testing and measurement uncertainties, as well as develop an understanding of the elements necessary to establish a successful internal materials verification program. Throughout the course, within each section of the syllabus, case studies will be used to solidify key concepts.


Supervisors, pipeline and facility engineers, and technicians responsible for ensuring compliance with PHMSA’s 2019 Gas Transmission rule; NDT service-providers; and related pipeline industry stakeholders will also benefit from attending the course.

On completion of this course, attendees will be able to understand:

  • Federal code requirements for a nondestructive testing-based materials verification program
  • Laboratory destructive testing for chemical composition, strength, and metallography
  • Measurement theory and data uncertainty
  • Theory behind common NDT tools that estimate strength and chemical composition
  • NDT tool validation
  • NDT measurement uncertainty
  • In situ metallography and microstructure quantification
  • Elements that comprise a successful internal NDT program
  • Methods for establishing grade and vintage from NDT data


Upon completion of the course, participants will be awarded 1.4 CEUs.


Complete course presentation material will be available as a PDF download prior to the course.
