Regarding the order of pressure levels for the following items: a – maximum operating pressure, b – highest allowable operating pressure, c – design pressure, d – pressure at which the safety valve activates, e – burst pressure of the rupture disc, f – pressure for pneumatic testing, g – pressure for airtightness testing.
Regarding the order of pressure levels for the following items: a – maximum operating pressure, b – highest allowable operating pressure, c – design pressure, d – pressure at which the safety valve opens, e – burst pressure of the rupture disc, f – pressure for pneumatic testing, g – pressure for airtightness testing. Sorting: e f c a d b g
There’s a trick in this question, right? The maximum allowable operating pressure isn’t compared with the pressure used for the pressure test; it can be either high or low
(b or f) > (c=g) > d > a
(b or f) > (c=g) > d > a
(b or f) > (c=g) > d > a
f g c d(e) b a
f>c>b>a>c=g>d=e

a- Maximum operating pressure < c- Design pressure < e- Airtightness test pressure < f- Pressure for airtightness testing < d- Pressure at which the safety valve activates < e- Burst pressure of the rupture disc < b- Maximum allowable operating pressure
