Calculate length of safety valves vent pipes.
Maximum length of relief valve vent lines
can be calculated as
lm = 0.56 (1.1 pr + 14.7)2 di5 / qa2 (1)
lm = maximum length of vent line (feet)
pr = relief pressure (psi)
di = inside diameter (inches)
qa = air flow (lbs./min)
Air, LNG, LPG and other common gas properties, pipeline capacities, sizing of relief valves.
Safety valves with boilers ranging 275 to 1500 kW.
Calculate pilot operated relief valves in liquid systems.
Maximum safety valve free air relief capacity.
The most common used safety valve standards in Germany, UK, USA, France, Japan, Australia and Europe.
Calculate spring operated relief valves in liquid systems.
