API 571 (Damage Mechanisms) Supplementary - Preparatory Training Course
Introduction:
Course Objectives:
To improve safety, reliability, and minimize the liability of fixed equipment by learning common damage mechanisms in the refining and petrochemical industry as covered in API 571. The roles of the engineer and inspector in identifying affected materials and equipment, critical factors, the appearance of damage, prevention and mitigation, inspection and monitoring will be covered to introduce the concepts of service-induced deterioration and failure modes. This course is intended for anyone interested in gaining a fundamental understanding of damage mechanisms in metals. The course provides participants with the knowledge necessary to:
- Successfully pass the API RP 571 ICP exam.
- Understand the subject matter on the API 571 exam. (Steel-Solutions guarantee).
- Have a detailed background on the scope, organization and use of API RP 571.
- Understand the relationship between various corrosion mechanisms and associated metallurgy.
- Identify various inspection techniques for the different metallurgies and corrosion mechanisms.
- Comprehend how various corrosion mechanisms react in specific environments (how they can be rate controlled).
- Understand general damage mechanisms applicable to the refining industry and be able to identify their features & functions.
Who Should Attend?
Engineers, inspectors, designers, and experienced maintenance personnel who are involved in designing, operating, maintaining, repairing, inspecting and analyzing pressure vessels, piping, tanks and pipelines for safe operations in the refining, petrochemical and other related industries. (Interconnected with API 579, API 580 and API 571)
