55 Gallon Drum: How much Air(PSI) will they Hold

- I am building an Oil Burner (Heater for the shop), and I have gathered a bunch of oil and drums.. One of which was damaged.. I figured I would test how much pressure it would hold and see if I could straighten it out.. Someone said, 3-5psi max.. I could not imagine that.. This was the test that I did to see just what it would take.. Cheers! The Results to me were very surprising... Enjoy..
Thanks a lot for sharing your experiment, I was looking for some thing like this.
Yea.. I'm glad I didn't bet any money on it.. It actually shocked me, it took such little pressure. Cheers!!
@@MarkThomas123 i tested my new steel drum yesterday as a boiler and when steam pressure inside gets to 4.4 psi I noticed that the lid is starting to bend outward, and that where I immediately stopped heating the water inside.
@@amintaleghani2110 Try an old water heater or a 100# Propane tank is even thicker walled. Not sure how much pressure they hold, or you need, but it holds compressed gas.
@@MarkThomas123 Thank you.
What About those plastic 50 gallon drums? Have you tested them. What about if reinforce the plastic drum with ratchet straps ( 3 tightened around the 3 different parts of the perimeter and 2 tightened crossing at 90 degree angles from the top end to the bottom end?
big thanks for the vids, but if you have time please do actual test, how much that steel drum can hold the air pressure.
The drum was starting to come apart at that pressure.. I would say another 5lbs and it would not have been able to sit straight.. They are not strong drums for that kind of pressure.
Death in a can. Actually I intend to make a chamber that goes up to 30 psi.
For oxygen treatment but 10 psi would be enough . I would like to see a new barrel taken to burst pressure.
For acience
If your test is accurate, 15 psi is the max pressure it can take. I would like to know what is the thickness of the tested drum.
Remember.. This was a "Bent" drum I was straightening out,, BUT,, the top and bottom also distorted at that pressure.. The sides popped out pretty quick. Way below 15psi. I don't think I would trust 15 psi as a max. It is where I stopped, and the drum was already rocking on it's end and the top was buldging out. The metal actually seemed like it stretched, but, I am pretty sure it was the area around the rim that bent out, not stretched.. But, you get the idea.. It will hold the weight (400-450lbs) is common.. Just not outward pressure.
Bet it would make a good air tank if it was poured in concrete.
I'm sure that would help.
@@MarkThomas123 I imagine it would hold hundreds of pounds of air pressure. The Drum would not be lending much strength to the operation at all only air tightness. Whether the pressure was able to bust the vessel on not would depend on the concrete.
@@herbertbell9438 Yea, plus if you put air in there, it will rust, so, not the greatest plan for the effort and cost. Keep your eye out for a good air tank, or, some other kind of pressure vessel.. Check to see how much pressure a Freon tank holds.. Might be able to connect several with hoses until you find a good tank.
Propane tanks would be another option. They can only get so old before they have to be retired.. Not sure of the pressure capacity, but, if you only need 90 psi or something like that, it might work...
I was just wondering if I could straighten out the drum and use it to store oil... Ha...
@@MarkThomas123 I'm just thinking about what might be possible. Say in a SHTF type situation and you needed some compressed air. It would probably even work with a plastic drum thinking about it. The strength comes form the concrete so you could probably even blow up a thick trash bag and pour cement over it if you could somehow get a pipe to fit on a thing like that. As long as the air doesn't get into the pores of the concrete it should work at lest for a quite a while. In the case of a plastic drum maybe a long while. It's hard to say though, probably no one has ever done it.
@@herbertbell9438 Put some fiber and reinforcement wire in your concrete, just for safe keeping.. Might even be able to pour a form of some type, leave a square hole in one end of the concrete form, coat the inside with an Epoxy to seal it, and use two metal plates inside and out for your bulkhead and use some silicone or maybe better some construction adhesive to seal around the metal plates.. Weld around your air fitting, cut the bolt heads off you used to pull the plates together and weld those up solid one at a time.. The weld shrinkage would pull it back tight I would think...
Then, burry it in the ground,, just in case.. Ha...Ha... :)
Or, find some boiler mechanics in your area and have them keep an eye out for a used tank for you. Could also search industrial scrap yards for a piece of steel pipe and some flat plate and build one. Probably would want to do some research on boiler thicknesses and PSI, etc, just to stay on the safe side. I think water pressure tanks might be an idea also. They run at 40-60psi, so, are probably rated at 60 to 90, but, might surprise you, but, error on the side of caution. If something you build ever bursts, there is likely going to be flying debris, or, at the least, some portion that splits and flies away, likely with sharp edges and speed, which if you were standing close could give you something to worry about for a long while... You can always find old air compressors with blown heads or motors, and just the tank is left at junk yards, etc..
Especially if you take a Card of some sort to the local junkyard and tell them to keep an eye out and call you when they have something. A $20 tip should go a long way in finding something much better than what you are contemplating, and probably less expensive in the long run..
I wanted some different size coil springs to make some chisels, tools, etc, around my shop.. I told the guy what I wanted and the NEXT Day,, he called me and had more than I thought I would find searching myself in 2-3 months.. They know what they have out there.. I think I gave the guy $40 and had just about every size I could think of. Anything from Bicycle seat springs, to Motor cycle shock springs, to 1-2 and 3 ton Coil Springs from some old equipment they had sitting waiting to crush.. He just took a torch out there for an hour and cut everything I needed.. Worth a shot for sure..
I can just about guarantee you, your local "Dump" who recycles has a place to deposit metal items.. If someone is on the lookout for something that will hold air for you, guaranteed within a week or two, you will have your choice... Just give them your Cell and let them send you some pictures..
Good luck with the Project..
This video gave me so much anxiety
Waiting for it to Explode?? Ha.>Ha.. :)
Hey, I thought 50lbs, but, started being cautious when I first put the air in and stopped several times, but, pushed it up to 10 and 15psi before I figured any more would make it come apart.. Not too worried at 15psi it doing too much.. :)
Yes! Haha we have a harbor freight transfer pump that goes into a barrel like this and you use the air pressure, every time I do it the lid blows up real big and scares the crap out of me haha
@@theSkavenger84 Use a Pressure Regulator and keep the pressure low.. Between 3-5psi.. You really need volume and not pressure.. Might try a raft pump, or, a Mattress pump might work..
I have a raft pump with a pressure regulator that goes up to 3.5psi and it does nice.. It is the same motor/blower/vacuum pump that is in a central vac system. You can look at it here..
rivergear.com/product/man-of-rubber-mini-hurricane-turbo-raft-inflator/
Horse and dog groomers use them to blow dry off animals too, so, might find a better price on them.. It would be much faster. Your air hose probably only has a 1/4" air hole passage.. These have 2" hoses with a 1/2" air reducer at the end you can use or not use.. Pressure regulator built in if you ask them to add one.. Standard for rafting Companies.. It is a Leafield A6 Pressure Release valve. You can see it here.. Video shows it is a 2 part valve and you can see how it works..
www.nrs.com/product/1484/leafield-a6-pressure-relief-valve
I have made them before with some 6" PVC, and PVC Caps on the exhaust end, and fixing the pump with some weather stripping and some L brackets inside the PVC pipe, and some PVC fittings that you might have to heat to get to fit on a hose of some sort..
Anyway.. If you are just pumping out of a drum, you don't need pressure, just some pressure, but, enough to displace the oil with air.. You can get a nice stream..
Or, an Oil Pump out of a car engine, that has a shaft you can get a drill on, and drill both sides just right and thread it on both ends and screw in some 1/2 or 3/4 Galv pipe and put some garden hoses on it, and use a good 1/2" drill to get a medium stream of oil.. I have tried all of the above, but, the blower is the best route..
Call some Central vac shops and tell them what you want.. They get used units from time to time.. Good Luck with that.. But, if you keep your pressure down, or, add a T and a valve, you can let the air go and let some of it release out of the drum and just keep an eye on your flow for now.. Take the Anxiety out of it.. Might be able to rig up some pvc pipe with a plastic sheet over it with some rubber bands that will let the air leak out and make a home made pressure release and add more rubber bands until you get what you want... A couple of ideas to get you where you want to be... :) Cheers!!
Yup,how psi drum can hold until explode,and then measure thickness of drum wall
I am pretty confident that the Seams would fail before the metal would stretch thin.. The seams appear to be folded seams.. The welded seams only appear to be down the side of the drum, and are not folded.
But, there may be some stretching or thinning at the seams when they unfold. I think the top or bottom would fail first. Thank you for your comment.
Ah crap!!! I wanted to see it blow lol
Ha.. I think I was fairly close.. If I get a few more drums,, might just see what gives first.. Ha..Ha.. I'll put it behind something I don't care too much about and let her rip..Ha.. :) Cheers!
I did that once and sent the drum flying about 40 feet in the air
I was wishing you could put up to 35-40!pounds to use it as a water pressure tank
Better stick with a Water Tank with a bladder if you want any amount of Flex back pressure, or a Water heater, etc..
The question is: how much pressure does gasoline produce inside these drums ?
Gasoline Vapors would surely expose the inner workings of the seams, if a spark were present.
But, if it is Cold outside, you can drop a cigarette and often a match and it will go out when it hits the liquid.. Yes.. It's true.. Cold = No Vapors..
@@MarkThomas123 the question remains unanswered.
Ok.. Gasoline does not produce any pressure at all just sitting in the drum. Only the pressure applied to the inside of the container where the gas or liquid resides. I think it would be more proper to say "force exerted than pressure at this point". Like filling a balloon with a little water, less force is exerted than more water would exert. Gas would be less than water, since gas weighs less than water does.. If you are talking Expansive pressures, then, you have to start using some extra variables.. Like what is the temperature, at what level of atmospheric pressure, what barometric pressure if you want to get really detailed, but, a drum is designed to hold a liquid, and not under pressure. So, any liquid not under pressure would be roughly the same, only differs would be based on the density or weight of the liquid.. The force exerted on the drum for a higher density liquid (Heavier) would be higher than a lesser dense or lighter liquid.
Now, if you are talking about liquid converting to a gas, there really isn't much difference either, but, considering lots and lots of variables.. Like Propane under pressure will go back into liquid. But, if you ignite the gas, which are we talking about? Throw a match into a bean can full of gas and what happens?? The same thing basically as your Fondue pot.. But, what if you put a lid on it and sit it in the sun and do the same thing?? Poof!! What if you filled a gas can with a top half full, dropped a flame in, and closed the lid real quick.. If it were plastic, not near as much as a metal drum, etc..
Not sure what your question is, but, that info should give you some more details to be able to ask it.
@@MarkThomas123 then why my drum looks like it's under pressure and when I open the cap, pressure is released ?
Maybe because it's my imagination.
@@tonycstech Really?? Ok.. Want a simple answer/explanation for that?? I gave you a bunch of physics to think about.. Didn't know it was something that simple you were wondering about..
You didn't give a scenario.. But, with that one, it's pretty simple.. The temperature of the fuel in the drum is warmer than when you put the cap on before.. Everything expands when it heats up...
Want to see the reverse? Loosen the cap on the drum, roll it out in the sun, let it warm up a little,, then, tighten the cap and leave it in the sun for a while longer and watch it start building pressure.. Then, roll it back into the shade or shop or, where it is cooler.. Next time you see it after a couple of hours it will be just the opposite.. Or,, take a beach ball, inflate it lightly, where it is still soft, put it in the sun for 15 minutes and you will be able to go back and bounce it like a basket ball.. Make sense??
We would put 70 psi to blow out the dents all day long.
I highly doubt that. You may have set your regulator at 70psi, but, you didn't bring up the pressure "IN THE DRUM" to 70PSI. I would bet a paycheck on it..
If you did, and the drum somehow survived, which I would bet a paycheck against, it sure as hell would not sit flat on the rim any more..
This drum both the top and bottom bulged (not sitting on the rim) at less than 10psi.. 70??? Ha..Ha..Ha..
I have looked at a lot of drums and never seen one built that would withstand 70psi.. Why would you build one like that, if 3-5psi like this one could hold the 400 or 450 pounds of liquid material? Ain't happening. But, feel free to experiment on your own and upload a video to show me I'm wrong..
Make sure you capture the drum blowing out and show us the after effects.. I would say, keep an eye on it around 25 psi. That would be my best bet on the top/bottom seams blowing out,, if not before.. I am ABSOLUTELY CERTAIN, If I had gone above 20-30, this drum would have split the top off..
I think you need to look at the video and pay attention to what I was saying before you advertise your Computer or phone that you have some serious "Keyboard Driver Errors".. Someone else might actually think you have a clue about what you said and do something OBVIOUSLY STUPID,, based on this video..
But, like I said.. I did the video as an experiment and documented my findings.. If you are sure enough to "Blow Out Dents All Day Long with 70psi", then, why don't you video you doing this and educate the rest of us.. But, since this is a challenge, make sure there is no funny business with the Gauge and hoses not in sight..
Obviously, my video was educational and, I had nothing to hide.. Ha..Ha..Ha.. Some People!!!
BTW.. I like your CZcams ID.. @user-lm5eo7hx4n What is that? Someone paying you to go around and make ignorant comments for others to see and try some bullshit like that?? What do you have? 50k Different Id's???
I would not put it past being funded by the Current Admin to be honest with you... I stopped being amazed by anything they do these days..
As long as they can work at 30 psi, I could use them for my drip irrigation system that runs at 10 psi max
Water heaters and Pressure Tanks will hold that.. I run my deep well at 40-60psi and never had a tank give out that didn't have rust pin holes first.
What, are you worried about wasting film. What a stupid waste of time for me to watch your video shows everything except what mattered.
If you missed filming the event, start over. Duh
