How to select a safety valve?
Thread Content
What factors should be considered when selecting a safety valve? PS: I asked a question about unit conversions in T*T yesterday, and some forum members criticized me for being simplistic; I really don’t understand these things – my knowledge is limited. But the spirit of Kaichuan is to be helpful; everyone has knowledge that they are not aware of. Every tool has its limits; every person has their strengths. The sea and rivers ensure equality for everyone, providing everyone with the opportunity to learn*. Thank you, Haichuan!
Safety valves generally require GB/T 12241—2005
Please refer to the thread on the forum titled “GB/T 12241-2005 Safety Valves – General Requirements”: http://bbs.hcbbs.com/viewthread.php?tid=249948&highlight=%B0%B2%C8%AB%B7%A7%2B%D2%BB%B0%E3%D2%AA%C7%F3.

Even if you think on instinct: pressure level, temperature, medium, pressure release amount
