High Pressure Cylinder Identification

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.

Amazing video!!! I wish they taught this stuff in High Schools...seems like very good common sense. God bless you sir!

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~!!!

Good video. To most people the cylinder markings read like secret code. This made sense of it all. Thanks.

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.

How is the volume of a cylinder identified? (The cubic ft)

At 5:35 there is this marking "REE 265"? What is the meaning? Thanx

Thanks Nathan. I'm new to compressed gasses and I found your video quite informative and useful. Best Wishes n Blessings. Keith

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.

What do you mean 125 can only be rented or leased? I own a 125. With a slick neck ring

Thanks, you answered my questions expertly

How can that lead seal melt at 212f when the melting point of lead is 621f? Did I miss something? 😊

Thanks. I learned that the tank I bought at an estate sale was manufactured in January 1953 and was last inspected in October 1972. What is a reasonable charge for the test? Got quoted $49.95 today.

[adamholmes]

Next to the test date stamp on the tank to the right, theres another marking labeled "REE 2...." What does that label indicate?

[jordananders]

Just because your company only leases the larger cylinders does not mean that they are only leased cylinders for everybody. Where I live, you can own any cylinder, and refill any size.

Thanks for the information ℹ️
it was very useful to me

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 .

If one was to cool air down to a liquid, how much of it would reasonably safely fit into a G size cylinder (which hold about 353 cubic feet of oxygen I think)..?.

I own my k tanks. Every time I take them in to be filled they try to keep them until I bring in the titles. I'm taking them in this weekend to be filled again. Yes, I'll take the titles but it is getting to be a pain after over 30 years.
