Max. backpressure conventional PSV for fire case - Chemical process engineering. API RP5. 20 part I, section 3. In a conventional pressure relief valve application, built- up backpressure should not exceed 1. A higher maximum allowable built- up backpressure may be used for allowable overpressures greater than 1. It is my interpretation that when we have a PSV for fire case only, I can use a conventional relief valve provided that the built- up backpressure stays below 2. However, the wording "may be used" in the API 5.
In this particular case we have a relief valve that reliefs directly to atmosphere. What is your opinion here?
