Have you ever seen a container with this structure?
Thread Content
I encountered a nitrogen tank. The two ends of the tank's barrel are threaded and the flat lids are screwed in. Is this structure allowed? The design pressure is 21.2mpa and there is no welding after screwing. If allowed, can you tell me what specifications or standards support it?

After screwing it in, it should be welded again.
What are the pressure, volume, and temperature of nitrogen?
In this case, the pressure is usually relatively small or the diameter is relatively small, right? Threaded connections are also acceptable as long as sealing can be ensured.
Usually the pressure is relatively small or the diameter is relatively small.
This structure should be used when the pressure is relatively small, as long as there is no problem with the sealing
There should be special regulatory controls for storage tanks like this, but unfortunately I have not come across them.
If the pressure is small, threaded connections should be used.
Some high-pressure vessels also use threaded connections. This depends on pressure, temperature, medium, working (storage) environment, and comprehensive considerations.
It’s very stressful, more than 20 MPa
This should be due to people's usage needs. It may need to be disassembled for internal cleaning or something.
It should be a small-diameter high-pressure vessel sealing structure. The sealing does not rely on threads. There should be a metal sealing gasket inside.
