Help Nitrogen. There's something wrong with my tank.

[Justnotme]

Does anyone have any idea why my Cylinder is yellow on top and slightly below?
I read that in my country, ammonia cylinders are painted yellow. Could it be that this cylinder was previously used for ammonia, and then nitrogen was poured into it?
Or is there ammonia instead of nitrogen even now?

Yes, the paint is coming off my tank because it's not new. But you can see that there is a gray color under the black color.
And at the top and slightly below, for some reason, yellow

Guys, please don't be mad at me for asking such questions. I have so little strength that I can barely move, so any thought process is difficult for me

If there is only some ammonia in the cylinder you would smell it - it has a very characteristic pungent smell.

Mine has a lot of flaking after having it for a long time, but the PSI is still at 1600 after 21 months, so everything's fine
When you turn it on, just keep checking the PSI, its usually at 2200 PSI if its a new tank
