Sizing, Selection, and Installation of Pressure-Relieving Devices in Refineries-Part II, Installation

Standard Details

Covers methods of installation for pressure-relief devices for equipment that has a maximum allowable working pressure (MAWP) of 15 psig (1.03 bar g or 103 kPA) or greater. Pressure relief valves or rupture disks may be used independently or in combination with each other to provide the required protection against excessive pressure accumulation. The term "pressure relief valve" includes saferty relief valves used in either compressible or incompressible fluid service, and relief valves used in incompressible fluid service. It covers gas, vapor, steam, two-phase and incompressible fluid service; it does not cover special applications that require unusual installation considerations.
