PSM 220: Overpressure Relief and Flare Analysis

DURATION: 3 Days, 9AM-4PM

COURSE DESCRIPTION
This seminar covers the application of relief devices for preventing over-pressure and under-pressure in equipment. The attendee will learn the requirements for designing and documenting pressure relief systems and specifying relief devices for those systems.
