Course Description

This Pressure Relieving Systems virtual training course will provide attendees with practical experience involving Pressure Relief Devices (PRDs). This virtual training course covers proper sizing, selection, and installation of PRDs to ensure adequate overpressure protection is provided and reduce hazards if a PRD discharges. The course content includes 3% inlet pressure drop requirements, sizing of PRDs in two-phase flashing service, and operation of PRDs and the effects of back pressure on valve stability and performance. In addition to the API 520/521 Standards (including content from the newly published 2020 editions), the course also covers protection of atmospheric storage tanks per API 2000 Standard and boilers per ASME Boiler & Pressure Vessel Code, Section I. The instructors will discuss the background and logic behind the document procedures and intersperse some example problems.
