Can a pressure vessel at atmospheric pressure be filled with nitrogen?
Thread Content
Can atmospheric pressure vessels be pressurized with nitrogen? Are there any regulations and technical standards related to pressure vessels? Is there a maximum limit for nitrogen pressure?
Of course not, pressure means there is stress, it’s dangerous!
Sure. Temporary material pressing leading to increased pressure can occur without affecting the return pipe; see Return. Although it is not a chemical storage container, a strong core is still necessary
Nitrogen pressure feeding is acceptable; 1. for short periods of time, and 2. as long as the pressure does not exceed 0.1 MPa
Adding a buffer tank should work; also, should it be used continuously or intermittently?
If the material is pressed in using nitrogen into this atmospheric pressure vessel, I think it’s possible. Isn’t this the same as using a centrifugal pump to feed material in? A so-called atmospheric pressure vessel should have an opening that is connected to the atmosphere; when nitrogen is fed in, it will flow out through this opening, and no pressure buildup will occur.
But if the material is pushed out using a pressure vessel at normal pressure, it shouldn’t be possible. As mentioned, a pressure vessel has an opening to the atmosphere – so how can pressure be built up in it?
