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. 

The code requirements for pressure relief devices are covered by the following ASME Boiler and Pressure Vessel Codes and ASME Pressure Piping Codes:

    ASME Section I – Power Boilers
    ASME Section III – Nuclear Systems
    ASME Section IV – Heating Boilers
    ASME Section VIII – Pressure Vessels
    ASME Section XII – Transport Tanks
    ASME Section XIII – Overpressure Protection
    ASME B31.1 – Power Piping
    ASME B31.3 – Process Piping
    ASME B31.8 – Natural Gas Piping
    ASME B31.12 – Hydrogen Piping

In addition, the following American Petroleum Institute (API) standards will be discussed:

  • API RP 520-Parts I & II Sizing, Selection, and Installation of Pressure Relief Devices
  • API RP 576-Inspection of Pressure Relief Devices

By participating in this course, you will learn how to successfully:

  • 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 

Who Should Attend?
