Pressure Relief Devices: Design, Sizing, Construction, Inspection and Maintenance
About This Course
Possibly the most important single safety device on a boiler or pressure vessel, the pressure relief device (PRD) is all that stands between overpressure conditions and catastrophic explosions. This comprehensive review of the design, construction, installation, operation, inspection and maintenance of pressure relieving devices currently in use on boilers and pressure vessels details how to protect pressurized equipment from exceeding the maximum allowable working pressure.
Learning Objectives
You Will Learn To:
Explain the Code requirements for pressure relief devices covered by the ASME Boiler and pressure Vessel Code and the ASME Pressure Piping Codes
Identify the design, construction and manufacturing requirements of pressure relief devices
Select materials for various types of pressure relief valves, and rupture disks
Explain how to apply the API RP 520 Part I, Sizing and Selection of Pressure Relieving Devices, API RP 520 Part -2, Installation of Pressure Relief Devices, and API RP 576 - Inspection of Pressure Relief Devices
Perform calculations for sizing and selection of pressure relief devices for single phase flow of fluids
Explain how to handle transportation, storage, installation, and maintenance of PRD's
Identify the requirements for testing and testing facilities
Explain how to perform inspections as per the National Board Inspection Code (NBIC), and API standards
Describe how to establish a National Board VR (valve repair) certification program and repair PRVs
Explain how to test pressure relief valves as required by the code
