Subject: [PSUBS-MAILIST] propane tanks revisited

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
lant - 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.
