Propane Tank investigation:
I was explaning my design to my diving friend and he mentioned that since
my pressure hull is around 28" in diameter that I might consider a propane
tank. I have always discounted the propane tank idea because I felt
having to deoderize it wouldn't be worth the effort, but then we discussed
buying a brand new one -never been used - from the factory. I didn't
think that would make any difference whether you were buyng a new one from
the factory or having one rolled from a fabrication plant -
but - he pointed out that since the propane tanks are mass produced
that they are cheaper ! So I called a propane company that I know and sure
enough they are a lot cheaper . For a 250 gal which is approx
30" X 7' the cost was $850.00 compared to $2000.00 (a
year ago) having it rolled at a fab plant. I still have to find out the
exact specs on the propane tank however, I'm not sure on the
thickness and I haven't confirmed the grade of steel.
