This Damage Mechanisms training course covers an overview of basic metallurgy and a description of the most common refining processes. Its major focus includes detailed discussions of the key refining damage mechanisms addressed in API RP 571 and examples of equipment damage and failures. It also includes discussion of typical Non-Destructive Evaluation (NDE) methods applicable for detection of damage related to the specific damage mechanisms. Many problems can be prevented or eliminated if the precursors to damage are observed and monitored so that any potential damage is mitigated. This training course will teach attendees to Identify Damage Mechanisms and Potential Risk Areas. The instructors will discuss the background and logic behind the document and provide relevant case histories.


  • An overview of basic metallurgy applicable to refinery construction materials
  • A description of common refining processes on the Process Flow Diagram level, highlighting where various damage mechanisms are usually observed
  • A discussion of typical NDE methods and their ability to detect and characterize equipment damage
  • Detailed discussions of the damage mechanisms that are found in refineries covered by API RP 571
  • Examples of equipment damage and failures, as well as learning exercises for students


Upon completion of the Damage Mechanisms training course, students will have a basic understanding of the following:

  • The relationship of API RP 571 to API 579-1/ASME FFS-1 and API RP 580/581
  • Major refining processes
  • Identifying common damage mechanisms and their locations
  • Typical non-destructive examination methods for detecting damage
  • Appropriate mitigation and monitoring methods


  • Refinery inspectors
  • Mechanical and maintenance engineers
  • Process engineers/operators involved in Fitness-For-Service, Risk-Based Inspection and fixed equipment reliability programs
  • Central engineering staff
  • Consultants for refining and petrochemicals

Although damage mechanisms associated with refineries are the main focus of the class, personnel from related industries (such as mid-stream companies, gas plants, and petrochemical firms) will also benefit from the course content and exercises.
