This has all been discussed more than a few times.huskers said:I would like to stack mine like that. The welding shop was uneasy about welding into my cleaned out tanks saying the metal would still contain possibly explosive material in the pores I guess. Is that possible?
I called around to find a shop that would weld on used propane tanks, and when I dropped my tanks off to have couplings welded on I asked the proprietor what precautions needed to be taken. The guy looked at the rusted port threads and said is was obvious that the tanks had been out in the weather for a few years and that it was impossible that an explosive mixture remained. So then I asked them what he would do if he needed to and he said just move enough air through the tank to be sure it's too lean to ignite.What precautions did u guys take? I thought may filling with dry ice or bottled CO2. I was just looking for a bracket welded to my 250 I want to mount vertical for expansion.
For horizontal there was a nice one posted not too long ago where they welded in 1.5" or 1.25" pipes horizontally into the ends of the tanks, one on the top and bottom of the end of each tank. The top of the bottom tank went out to a U-turn into the bottom of the top tank, and of course the system connected to the top of the top tank and the bottom of the bottom tank. All connections were on one end of the assembly where you could get at them behind a panel if you ever thought you needed to.He wanted to make something that would bolt together clamping around the tank to avoid welding. I was just going to put the 2 500 gal tanks side by side but I'm envious of yours and hate to waste space in my shed. Any words of wisdom?
Guess I should find out who welds on tanks around here. What about your floors? Mine is just 4" concrete, don't think that would handle 5 tons in one spot.
