This course is structured to provide the delegates with the appropriate mix of technical fundamentals and practical best practices to maximize their learning. The material presented demonstrates some concepts that are not always shown or described in textbooks. The course emphasis is on developing a practical understanding of the inspection and maintenance requirements for fixed equipment and piping systems in process plant applications. Sample problems and participant exercises are included throughout the course to illustrate the concepts discussed and provide the delegates with practice in applying them.

By the end of this course delegates will be able to:

• Apply the requirements of the relevant industry standards and practices to the inspection and maintenance of pressure vessels, heat exchangers, piping systems, and aboveground atmospheric storage tanks.
• Develop inspection and maintenance programs for process plant equipment and piping systems.
• Prepare appropriate details for repairs and alterations to process plant equipment and piping systems.

Engineers, Supervisors, Plant Operators, Managers, and other technical personnel who are responsible for the inspection, fitness-for-service assessments and maintenance of pressure vessels, heat exchangers, aboveground atmospheric storage tanks, and piping systems
