Why Choose this Training Course?

Why Choose this Online Training Course? 

This PetroKnowledge online training course is conducted for all professionals who are interested in understanding deeply the different types of corrosion, cracking and other damage mechanisms that their equipment may suffer or face in service. The following assets and equipment may suffer from damage mechanisms derived thorough API 571:

  • All of process piping designed according ASME B31.3 & inspected according API 570
  • All of Pressure Vessels designed according ASME Sec VIII & inspected according API 510
  • All of Tanks inspected designed according API 650 & inspected according API 653

This PetroKnowledge online training course will demonstrate deeply all the 66 damage mechanisms contained in the recommended practices API 571.  The damage mechanisms in this recommended practice cover situations encountered in the refining and petrochemical industry in pressure vessels, piping, and tankage. The damage mechanism descriptions are not intended to provide a definitive guideline for every possible situation that may be encountered, and the reader may need to consult with an engineer familiar with applicable degradation modes and failure mechanisms, particularly those that apply in special cases.

This online training course will highlight:

  • Basics of Corrosion
  • Understanding deeply the whole Damage Mechanisms as per API 571
  • How to determine which damage mechanism you may face with your plant assets
  • The Best Methodology to study for the exam
  • Real Exam Tricks & Simulation

What are the Goals?

What are the Goals?

By the end of this PetroKnowledge online training course, participants will:

  • Be very familiar and aware of all the 66 damage mechanisms stated in Recommended Practices API 571 as well as the different types of corrosion and cracking mechanisms
  • Be able to distinguish and identify the type, extent and severity of the damage mechanism faced in the plant facilities
  • Learn to anticipate which equipment may suffer specific damage mechanisms under which design and operating conditions
  • Know how to inspect for the damage mechanisms and recommended types of inspection methods
  • Know how to prevent the occurrence of the well-known damage mechanisms
  • Get prepared for the next API 571 exam and have enough knowledge and skills to pass such exam in order to get the API 571 Inspector certificate
