Pressure Relief Devices: Design, Sizing, Construction, Inspection & Maintenance

alt text

Pressure relief devices, also known as the "last line of defense" for pressurized equipment, are critical for the prevention of catastrophic failures during overpressure conditions.

This course is a comprehensive review of the design, construction, installation, operation, inspection and maintenance of pressure relieving devices currently in use on all types of boilers, pressure vessels, tanks and piping. The code requirements for pressure relief devices are discussed, as covered by the following ASME Boiler and Pressure Vessel (B&PV) Codes and Piping Codes:

  • ASME Section I - Power Boilers
  • ASME Section IV - Heating Boilers
  • ASME Section VIII - Pressure Vessels
  • ASME B31.1 - Power Piping
  • ASME B31.3 - Process Piping

The following European Code will be reviewed, and its application will be discussed in detail:
EN ISO 4126 - Safety devices for protection against excessive pressure

In addition, the following American Petroleum Institute (API) standards will be discussed:
API RP 520 - Part I & II Sizing, Selection, and Installation of Pressure Relief Devices
API RP 576 - Inspection of Pressure Relief Devices

Participants will receive a copy of the ASME Code, PTC 25 - 2014 Pressure Relief Device, and a copy of the book, Pressure Relief Devices: ASME and API Code Simplified, by Dr. Mohammad A. Malek.

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
  • 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
