I think the important point as sated before is that this rating is for water not air. These two things behave totally differently.

The odds are there will not be a failure or even if there is one it probably wouldn't be bad, but if there is a failure there is a chance that it could be catastrophic and very dangerous. This is simply not worth the risk.

You don't need to use expensive metal tanks. Black iron pipes in sufficient sizes are cheep and available at most of your big box hardware stores. There are also multiple fittings available to make the job even easier.
