Mechanical Design and Maintenance of Pressure Vessels Course
Introduction:
Course Objectives:
The course shall focus on predicting the degradation in service, setting optimum inspection intervals (API 580-581), projecting remaining life based on generic data corrected for plant-specific conditions to determine whether the equipment is fit for continued service or should be repaired or replaced (API 579, ASME B31G, etc.)
Who Should Attend?
The course is intended for Maintenance/Plant Managers, Mechanical Design and Maintenance Engineers, M&I Engineers.
