I'm wanting to mount oxy acet tanks horizontal under the cross bed tool box of a pickup. To the best of my memory, the reason not to use a acetylene tank that's laying down, is because it would draw much more acetone out into your stuff. There may be other reasons why, that I don't know. Anyway, If I were to put a length of pipe or something between the valve and regulator, roll the horizontal tank so pipe extension is vertical, would that prevent the problems that happen when using a tank on it's side? My thoughts are the gravity would help keep the liquid from reaching the regulator. Any thoughts or reasons why or why not this would work?
Reply:Acetylene gas is dissolved into acetone the liquid solvent. When the bottle is tipped, the liquid goes out the valve. Acetone can dissolve hoses and seals. If you need to run it horizontal, use Propane or propyleneTeach Ag Mech - Mike At Home:Lincoln Electric AC225Miller Challenger 172Gas AxeWork:eclectic bunch of 90's vintage blue boxes
Reply:yea it gums up regulator to. I realize it would come out of the valve. that would be the reason for the extended vertical run of pipe or whatever.
Reply:No. You just don't use acetylene cylinders lying down. Period. The only exceptions are older MC and B cylinders that were originally made to be used sideways on motorcycles and busses for acetylene head lights.Acetylene is a dissolved gas. It needs to "boil" off to come out of solution, much like CO2 comes out of soda. The porous material in the cylinder helps control and contain both the acetone and acetylene. There is a "space" at the top of the cylinder that allows the acetylene to collect so you get a gas you can use. By "space" I mean it's still full of that porous material, just not acetone. Turn that cylinder sideways, and now the valve is below the liquid level and you get acetone coming out. That acetone helps keep the acetylene compressed in the cylinder stable. If you take enough acetone away, the acetylene can become unstable and self combust. A BAD thing.I guess if you got enough old style B cylinders with the offset valves ( so even laying down you are still withdrawing gas from the "top" of the cylinder and manifolded them together, you could create a big enough system to be semi useful. It would be a piping nightmare, with tons of of places for acetylene to leak, not to mention the fact you couldn't transport them piped like that per DOT regs as well as safety issues. Turning on all those cylinders would also be a royal pain...The short answer is it just will not work, period..No government ever voluntarily reduces itself in size.

Reply:Why not convert to something like propylene? It's cheaper and with acetylene you never use the full tank, well you might but it's dangerous. With the cost of the wasted acetylene after 4 bottles, you could've purchased 5 bottles of propylene. There's a formula to figure out how much to use out of it but my instructor taught us that a rule of thumb is to not use it if it's below 50psi and if you do, you risk pulling oxygen backwards through the torch and into the tank and then there's a risk of explosion. Once the acetylene gets low enough, it can't un-desolve from the acetone quick enough which causes negative pressure and then creates the back-flow.
Reply:One other thing,If you happen to haul your Acetylene bottle laying down, you need to stand it back up, and let it resettle for at least an hour....I ruined a reg that way, I used it too soon, hauling it to the field one day to cut a old race off a shaft....[/QUOTE]Yep. Caught one of my guys doing that just the other day. Told him to get it in in the spare rack or he was buying the new reg and hose.
Reply:Thanks Mounce. I plan to keep everything acetylene though. Its simpler for me that way. I remember the 50lb thing, but if I'm using a small tip, I take that into consideration, and no purple flames

Reply:123 weld / 123 dead no advice needed! Use propane save life and money.
Reply:Actually a "Full" propane tank laying on its side will put out liquid propane till the level drops, it will withdraw and vaporize in the reg and hose frosting like crazy if the humidity is high enough!BTWNew BBQ tanks have a safety float that shuts off the valve to prevent over filling, this may also shut-off the flow if the tank is on its side......

Reply:I use propane for cutting, heating, forging and brazing. Save acetylene for welding. Save the money.

Reply:This started as a question, answered and explained by DSW. After that some of you want to make something else of my question, refer to me as stupid, or express your amusement of such. I don't have anyone say these type of things while physically present, nor seen much of it to others. I say the majority of you couldn't say what you wrote. Then I'm sure those big brave ones who would, cant, because your thousand miles away.

Reply:yes, you were the first to answer. I appreciate your response, along with some others. I just mentioned dsw because it was the most thorough answer before my question became jokeful for some. I appreciated your second post also in support to ignore the comments. Thank you teachagmech for your posts. I don't claim to be perfect or claim I haven't made any inappropriate remarks. I was going to quit when zapster said so, but it kept going, so I'm still responding. Thanks to those who tried to help, and no thanks to those who didn't. Those who didn't, please don't respond to any of my future posts. And I won't respond to yours.

Reply:I own all my own bottles, have a half a dozen victor torches, w/ oxy acet tips scattered everywhere I go. I have couple different trucks and trailers. I get my gases cheap, and usually on a barter from local fabrication shop. They don't use propane. If I were to start changing bottles and tips for one set up and different for another, and go to a separate outfit just to obtain propane, and remember to bring the right tips for the setup that I'm using, it would complicate matters. This way, everything is the same.

Reply:Originally Posted by ReverserHas anyone else besides me never heard of this? I've known of the risk of using acetylene at too high a volume according to the size of the tank.But have never heard of not being able to use up all the acetylene in a bottle without risk of the bottle blowing up. We always turned in our bottles with a little still left in them, but it was because we didn't want to run out when out on a job.
Reply:Originally Posted by teachagmechYou're not the only one. I use back flow presenters and change bottles when the tank pressure drops below proper working pressure.
Reply:I have read on several occasions of fires with the bottle on its side. Maybe coincidental and fire came about from something else I have no idea. You can run the bottle until your torch starts acting up.Sent from my SCH-I545 using TapatalkCRIME SCENES, COURT DATES, FUNERALS, RIDING THROUGH THE CITY WITH A BITCH THAT IS JUST BEAUTIFUL IT'S JUST BUSINESS AS USUAL. |
