ENGINEERS BEWARE: API vs ASME Relief Valve Orifice …
Witryna30 lip 2014 · Psv Orifice Selection - posted in Relief Devices Forum: Dear all, In PSV sizing, the required orifice area that I calculated is 1.282 square inches . Could I go … Witryna5) Justification of relief valve sizing. a) Line is pressurized by compressor as 1 step. Maximum compressor pressure is 10.3 barg and it is enough lower than design pressure for piping line 40.9 bar g (593.2 psi g). b) As 2″ step, line is boosted up to test pressure by N2 cylinder. Pressurization by N2 cylinder is controlled by regulator ... WitrynaThe combination correction factor for use of rupture disc [Kc] when rupture disc is installed is 0.9. Therefore for the critical flow behaviour the required effective orifice area is estimated as, (34) (35) From Table 1, the PSV chosen for a calculated orifice area of 2.11 in2 is an ‘L’ designated orifice which has an orifice area of 2.85 in2. restaurants in clintonville wi
