I posed this question on the end of a recent thread response but I'm really curious about the answer.
An HP tank, say a PST E7-100 fails hydro, is it finished? Or depending on the tanks response can it be downgraded to a lesser rating?
The LP tanks start with the + and get to assume the nominal rating as long as they fail in a certain range.
Even the MP tanks can drop back to the lesser rating.
I'm considering some HP cylinders and I'm wondering how close to the edge these things are operating.
