Before touching it with a torch, welder or grinder, unscrew the valve and flood it with water. The water will push out any source of explosion, whether its heavier or lighter than air.
The wall thickness of my SCUBA tanks (rated 2000#) is much thicker than a 20# propane tank and are pressure tested to 3000# every 5 yearsWith so many kinds of readily available sprayers to purchase why shake hands with danger? Large or small propane cylinders are not coated inside to resist corrosion.
Paint ball and SCUBA tanks are only meant for dry air.
There are some quart to several gallons spray containers made to be pressurized using a air compressor and are vary expensive.
It’s good that you ask a question. Hopefully you can understand why it’s not a good idea.
OK, I'll bite; why?You will get someone hurt or killed with that idea. Very stupid idea. Don’t do it.
I installed a tire valve in a one gallon plastic pump up sprayer and pump it up with an air compressor. It worked well but it ran out of air just as quickly as using the manual pump.I will admit to my total ignorance when it comes to pressurized storage containers and could use some help. I have had no luck trying to find answers to most of my questions on the net.
Here is an idea I have had for years and wondering if it can be safely pulled off. The goal would be to have a pressurized utility sprayer that I can carry around with me for spraying roundup etc. I am tired of pumping my 2-3 gallon sprayer every several minutes. I have a 5-gallon backpack model but once full I have a hard time getting it on/off by myself and it hurts my lower back as I walk around my 6 acres. I like the idea of a smaller, pressurized, hand held 2-3 gallon sprayer. I know they make battery powered units but I like to experiment & was wondering if an empty propane tank be repurposed (refilled with air) to provide the 10 PSI that I need? I do not think the high pressure paint-ball tanks is what I want as they are thousands of PSI and expensive.
I have long wanted to take an empty (small torch sized) 1-pound propane tank and refill it with air via my shop air compressor and try out my idea. I would attach a regulator to knock down the high pressure air down to ~10 PSI.
My 1st & most important question is what PSI can these small 1-pound propane tanks hold safely? The last thing I would want is to set my shop compressor too high & have a catastrophic failure due to too much pressure while refilling it. The next question would be where can I get a low-pressure regulator with a gauge so I can dial in the PSI into my 2-3 gallon sprayer.
Use a long hose. No easy way to accomplish what you seek.Appreciate the idea......would be fine but this is not for spraying hundreds of feet of fence lines or tree lines etc.....way too much close in spraying that must be done on foot.
Well, that's one reason. You don't understand the dangers involved.OK, I'll bite; why?
I have a 25 gal elec sprayer. I put the tank on top of the box blade of the tractor or on the fold down back seat of the golf cart. Works great.Buy a 15 or 25 gal spot sprayer, put it on your tractor in one of several places handy plug in to battery and spray all you want without the trouble you are looking at with your method.
Because PVC degrades in strength due to a variety of factors, including sunlight and some compressor lube oils. Mechanical external impacts can also cause the entire pipe run to shatter violently if filled with compressed air. The resulting explosion sends plastic shrapnel everywhere. It is an OSHA violation to use PVC pipe for compressed gases unless buried underground or completed encased in suitable materials.OK, I'll bite; why?
Purchased a 3 gallon 18 volt battery powered sprayer and have used it for 3 years and very [pleased with it Covers a decent range for spray pattern and this will accept Black & Decker replacement or back up batteries. Would purchase again. Has shoulder strap, but I normally just pack it around by the handle as I spray. Used on a acre plus with hills and a ditch thru the center. Rest of yard & ground is either mowed and baled. CDZI will admit to my total ignorance when it comes to pressurized storage containers and could use some help.
