How to identify the markings and size of Industrial High Pressure Cylinders

Thanks for the explanation! It helps to see a person standing next to the cylinders to help aid in figuring out how heavy they are and how to move them around.

Great video as this is exactly what I was trying to find on YT but you are the only one who explained it for us weekend warriors that have just got our hands on a MIG Welder that uses CO2 as a shield gas. So thanks for the fine audio and no background music that is so annoying. First Class all the way~!!!

I'd never deal with a welding supply company that restricted the size of owner cylinders. I've got a half-dozen bottles, ranging in size from 80cf to 250 cf, I used to have a 330cf bottle, but traded it for another 250, the 330 was a little bigger than I like to move around my shop. My welding shop takes my bottles, and exchanges them for full ones, so "your" bottle changes when you bring it in. I can't imagine insisting on getting "my" bottle back, but I suppose it could be done. Frankly, I don't care what the bottle looks like, as long as it's within hydro cert, has no ownership markings, and is the same size as the one I brought it.

My dad owned a 125 cu/ft O2 cylinder for 30 years that was made by his friends company: Mittler Supply (RIP Tom Mittler). Dad meticulously minted out the tank and painted it beautifully Green and Brown. He then dropped it off at Knoxville Holston gases to be filled. Jerks lost his tank and gave him some beat up, worn out rusty oxygen tank and threatened to make him lease when he is an owner... Holston gases, treat your customers better.

Thank you so very much for this wonderful explanation and it really shed more light on my understanding about the sizes of and the markings on these gas cylinders.One thing that I just want to further understand is the size of a cylinder that is smaller than the 80 cu/ft and bigger than the 40 cu/ft, what size can that be.The 80 cu/ft is the Oxygen cylinder that I have and the other one that is smaller than the 80 cu/ft and bigger than the 40 cu/ft is the Acetylene .What size could that be.Thanks and I hope I will be able to get a response from you as regards this .

This guy full of crap I have been in welding business for 50 plus years I own over 45 bottles, I have bought bottles for years it doesn't make a difference how big they are and they belong to me. The company that I have been working with to fill my bottles went broke or sold out, now all these other so-called companies will not fill my bottles, they want to trade my bottles for their bottles they can go jump in the lake, I have too much money invested in new valve and nice paint jobs on my bottles I'm not giving up my bottles for rent. I do not lease the bottles to anyone I use them for my own use. All these welding supply companies think they own everything that way they can put the screws to you and charge you all they can. In Texas by law they cannot charge you rent on the bottles unless you sign an agreement on a pick-up day and a return date. When you buy the gas in a bottle it is yours until the bottle is empty. The only way they could charge you rent if they are a rental company.

​@@jordananders8525I've been in a welding business a machine business and supply business since 1976. It is not a question of ownership of my bottles, all my bottles has customer-owned on them, 75/25 mix, pure Argan, oxygen, acetylene, CO2, nitrous oxide, the problem is the companies that I went to said it was too much trouble for them to fill my bottles and return them to me, so they wanted me to give them my bottles and then they would not charge me rent on their bottles and they would keep me supplied or what I need. Back in 76 we did that with a company gave them around 12 bottles 3 years later they start charging me rent but did not replace my bottles a bunch of Thieves. So shame on me once not twice. So now I have no alternative but to drive 300 miles one way to have my bottles filled. The reason for that is nobody around here will fill acetylene. All these be high-tech companies want to cut the little man out like me, just like Walmart has done the mama pop stores.

@@sherwinstaudt1881 huh. Here in utah we have Humphries that will do fill only and give you the bottle back. most other places will swap out for one with a blank neck ring if you own the bottle, and all slick necks are considered to be COCs unless the bottle itself has ownership markings. Lindie/praxair gives me slick necks if I ask. Every area is different but only doing business with places that give you slick necks might be your best bet. And for the bottles that might have been de facto stolen, small claims court maybe? Sounds like a fairly easy case.

the Local Praxair and Airgas told me that my tank could not be traded in because of its size it is either a 125CF or 122CF with no ownership ring, there for it is a owned cylinder not a rental and it has lasted me about 4-5 years so far, but still denying a fill because of its size is a bad business model if your tank does not have a ownership ring.

Rent one slightly bigger and fill you’re original thank whit it and return it back the next day that way you only pay for the gas and you can fill up your thank and not pay rental fee. But you need to buy high pressure hose 2500 psi and have the right connection for the tank, bingo.

How often do cylinders actually fail testing is it like 1 out of 10, 1 out of 100. My dad gave me a older cylinder manufactured in 1941 also with a us navy stamp on it that last cert date is 66 and is rated for 1800psi and it’s a odd size to it as well it’s about 5 inches taller then my 80cf but is also skinnier then the 80cf. It has a cga540 valve on it for oxygen so what I’ve been thinking of doing is buying a transfill hose and just filling it myself from the leased tanks at my work.

can you please help me with the info on mine? i am in canada where i purchased mine,i believe it's a 60cf but i dont recall,either 60 or less,anyways there is no marking on the neck,here is what is marked on the bottle SPUN 5WH79+SCM 1{dash line with circle under it with vertical line in the center of circle}92 CTC 3A-2015 PF 11541 12(small 353) 06+star

@matthewmetzger5561 5 жыл бұрын
The SPUN is just a manufacturer info, Ctc 3A-2015 is the type of steel cylinder and max pressure it can be filled to, the PF 11541 is the bottle serial #, the 12(353) 06+* is the last date of test.12 [December] manufacture or tester RIN 353 and 06 is the yea of 2006. + means it can be filled 10% over bottle pressure and * means 10 bottle shelf life befor being needed to be retested from 12/2006, so dec of 2018 is the needed test to recertifications your bottle

It's actually a metal alloy similar to solder, not sure exactly what it it though. This is precisely the reason if you've ever taken a welding class at a trade school or community college for instance, one of the things you're taught is to never use boiling water to thaw a frozen valve or free a cylinder frozen to the ground since you could either melt safety plug or soften it enough to leak, and some cylinders, particularly larger acetylene cylinders, have a safety plug at the bottom as well as the valve assembly.

The DOT-3AA is not specifically a steel material designation, but rather a cylinder design standard. Take a look at 49CFR178.37. The hydro static test pressure is also 5/3 times the marked service pressure. www.ecfr.gov/current/title-49/subtitle-B/chapter-I/subchapter-C/part-178/subpart-C/section-178.37
