How to understand the \"maximum operating pressure\" in the definition of pressure vessels”
Thread Content
When defining pressure vessels, the maximum operating pressure is mentioned. What does this maximum operating pressure mean? For example, in a constant-pressure tower, 5 kilograms of steam are used in the reboiler; if there is a leak in the reboiler and the gas outlet becomes blocked, the gas pressure will be higher than 1 kilogram. How should this situation be handled? Thank you
It's hard to say anything about pressure vessel design when internal leakage is taken into account...
Abnormal operating conditions are not taken into account.
If steam leaks, there will also be the issue of phase-change condensation, and the possibility of overpressure will be much lower: lol
The maximum operating pressure refers to the pressure under normal operating conditions of the container! Ignore abnormal cases; otherwise it would be too complicated and wasteful! Abnormal situations should be resolved through other means!
Regardless of whether there is a legal basis for exceptional situations, or the interpretation of relevant laws
I have a related question here: do the relevant regulations specify any coefficient relationship between the maximum operating pressure and the design pressure of pressure vessels?
Is a container containing water at 10 MPa and 120° considered a pressure vessel?
If you think this situation can reach over 60, it’s something to consider. Don’t waste your thoughts on other things.
