Refilling Propane Cylinders..?

[e9999]

I have seen this in "da hood"
The store on the corner was the only place with nat. gas so the rest of the block had hooked up to them with garden hose and fittings .
I was called along with the gas and electric company since everything (gas,electric,cable and phone)was wrapped together running along the fences in the alley

cute! did the store know about it?

at least that's much lower pressure than what our own Jimmy was proposing to do...

So if natural gas is at a lower pressure can I use my drip hose and twist ties for this...

Try bendy straws the accordian creates a venturi. New guy here

Welcome,cool tip on the bendy straws,so the propane/natural gas will pick up speed as it travels along...

well, to get back to tech, I should note that I have seen some refilled little green 1 pounder that looked "inflated" after several refills. So these must eventually suffer from overuse.
Caution is in order I think.

why not....

take pictures

which brand? Coleman never has to me.....but that wallmart crap could I suppose

that's a good point. These are likely not all made equal.

I have seen the L-Cheapo's not even work new........that sucks when its cold out and you need heat:whoops:

One of the major problems with Propane..

When it gets really cold, it stays a liquid

lessee....

At -100F the equilibrium vapor is at about 3 psia or so, too low, below atmospheric.
It's atmospheric pressure at about -40F. Close to that would already be questionable for use I would think. Fortunately for me, it's not often -40F in Socal.
At 0F it's about 35 psia, OK for a stove or heater I would think, no?
At 75F about 130a psi or so. Not too much.

Where it gets a bit scarier is that at 100F it's already at 200 psia and it should not get too hard to get that high in the sun.
I would stay away from the black bottles just for that, btw.

ohhhhhhhhhhh dad it was not that cold.

Not if you warm the tank up by putting it in front of the heater.

How many things are wrong with that sentence?

Through a regulator, nope..

???

what pressure do you expect it to be on the downstream side of the regulator to feed a camping stove burner?

 

[cruiser88]

7 psi?
