Damage Mechanisms

By Brian Jack, Principal Engineer II at The Equity Engineering Group.

Course Description

This course aims to enhance your understanding of damage mechanisms and their impact on mechanical integrity in facilities. It provides an overview of API RP 571, Damage Mechanisms Affecting Fixed Equipment in the Refining Industry—the industry's primary resource on damage mechanisms.

The course covers reactor effluent cooler (REAC) systems, a very dangerous system in oil refineries. You will also gain a better understanding of two dangerous damage mechanisms: sulfidation and high temperature hydrogen attack (HTHA). Additionally, the course covers damage mechanisms affecting Amine Units, a comparison of inspection compliance programs with inspection excellence programs, and a brief overview of the most pervasive damage mechanism in our industry: external corrosion.

This course includes:

  • 1.00 CPD/PDH (certificate provided upon completion)
  • Over 1 hour of on-demand video, including comprehension checks and an exam
  • Access for 90 days upon beginning the course
  • Slides are not available for this course

What You’ll Learn

After completing this course, you should be able to:

  • Determine when and where damage is most likely to occur and assess susceptibility to damage
  • Understand design and metallurgy requirements/best practices for mitigating damage
  • Understand how process changes affect damage
  • Know where it’s best to inspect
  • Know how best to inspect.
  • Understand how process changes affect damage
  • Understand the importance of implementing integrity operating windows (IOWs) to control damage rates
