Relief Valve Orifice Sizes | API ASME - contractors unlimited
网页The American Petroleum Institute has developed a series of inlet size, orifice, outlet size combinations for various pressure classes of flanged relief valves. These combinations have been widely adopted by engineers throughout the oil and gas and allied industries.
网页The function of a pressure relief valve is to protect pressure vessels, piping systems, and other equipment from pressures exceeding their design pressure by more than a fixed, predetermined amount. The permissible amount of accumulation is covered by various codes and is a function of the type of equipment and the conditions causing the ...

Sizing and Selection of Pressure Relief Valves for High-Pressure
网页2021年12月1日 · A pressure safety valve (PSV) or pressure relief valve (PRV) protects a pressurized system or vessel during an overpressure scenario [1]. The term ‘overpressure event’ refers to any condition that causes the pressure of a vessel or system to exceed its specified design pressure or maximum allowable working pressure (MAWP) [2, 3, 4].
