I know that all vessels have to be protected from over pressurization, but what about these scenarios:
Air receiver rated at 150 psig, but the maximum discharge pressure of the air compressor is 125 psig. Am I correct in thinking because the system cannot ever exceed the design pressure of the tank, there should be no relief required.
Steam to glycol heat exchanger rated at 150 psig. I know there is a relief required on the water side, but the steam side (also rated at 150 psig) has 60 psig steam supplied to it. At the steam generator, the 60 psig system has reliefs installed with a maximum relief pressure at 80 psig. I would guess again that no relief is needed on the steam side.
Am I correct in these assumptions?
Thanks for the response.
