I am looking for a regulator I can use on a 2000 psi bottle (flamagle gas) that will step the presure down to 5 or 10 psi - maybe no need to be adjustable - output pressure could be fixed. Like a LP reg on a gas BBQ - except a high input pressure one. I got a helium baloon filler but soon discovered it outputs about 80 psi. a bit too high. ( is there in internal adjustment on these that could be turned down ? )Is there a simple and relatively inexpensive solution here? Thanks... TimLast edited by jethro; 01-19-2012 at 01:44 AM.
Reply:What kind of gas are you dealing with? Does the tank actually weigh 2000lbs or is it at 2000psi?
Reply:sorry-2000psi 200 cubic foot. Feels like it weighs 2000 lbs though ! Flamable gas- the kind that burns !
Reply:lol no problem. The type of regulator is dependent on the gas. Is it like acetylene or propane ?
Reply:Have you investigated a hydrogen regulator? That is the first flamable gas that might come in cylinders I could think of. I never had one but the paperwork that comes with regulators shows all sorts of variations for all sorts of gasses. Well at least for the oxweld r77 series. After looking at their website I think the paperwork had a lot more options than the website lets on. I would imagine others are similar though I havn't had the paperwork from those boxes in my hands. Strange you don't want to identify the gas. Is it duterium or heavy hydrogen? I have seen a cylinder labeled that once so there must be a regulator for it. Putting hydrogen and regulator in a search engine comes up with like $80 models in the paid spots at the top.Fran

Reply:Mr GBM,Did you fact check this video?My flowmeter has different graduations (like four on the four sides) on the clear part with the ball for different gasses. This guy has one where the graduations are for different machines.He speaks of a double flowmeter for a tig welder and a plasma cutter off the same bottle. It would seem more likely one for the torch and one for a back purge. I often wonder why all the talk of dry air for a plasma cutter when a bottle of nitrogen is certainly cheaper in the short term. Can you plasma cut with argon or argon/helium? What gas could he be talking about if the answer was no. Do you even use a flowmeter with a plasma cutter? As for the fixed output natural gas is generally something like four inches of water pressure but those certainly aren't designed to attach to a cylinder like in the origional post. They may be somewhat adjustable but the installer took care of that when the piping was installed.FranLast edited by fran...k.; 01-19-2012 at 08:06 AM.
Reply:If you dont want to identify the gas try google. just search for "regulator for _____ " . just fill in the blank with what ever is in the tank!!
Reply:Mr. Fran...K, Did you see the word " Might " ? That means that that subject needs to be investigated further. It does not mean ' yes' or ' no' ... it is a conditional situation which need to be checked out.Weldandpower Lincoln 225 AC,DC with Briggs 16hp gas engine.WW2 era Miller TIG.
Reply:I was only commenting on the content of the video. However this has kind of got me wondering about high pressure natural gas which could become a lot more common. Maybe forklifts will be running on that instead of propane as time goes by.

Reply:Originally Posted by AndyACarbon Monoxide, technically a flammable gas. Hopefully he's not messing around with this, but maybe that's why he hasn't responded.
Reply:Sorry guys I didnt get back to you sooner - I got the flu rite after i posted the question. I cant really say exactly what the gas is because I am helping a friend on his proprietary project.He only needs 5 or 10 psi output and probably it doesnt have to be variable. I believe it does have to be an actual regulator to not burst a low pressure line downstream of the regulating device. Perhaps there is not much commercial use currently for a fixed pressure reg off a 2000 psi bottle ? I have never seen one. Just wondered if yall had. Have been using hydrogen ones and the like - they work OK but we dont need the ability to adjust the output. The helium baloon filler might be the rite general mechanical arrangement except that the output is too high. I guess I could E-Mail the compannies who make those with a question about lower output pressure models ?I hope that clarifys the question some ......Tim
Reply:Sounds like Silane gas to me.JanErik"The trouble with quotes on the Internet is that you can never know if they are genuine." - Abraham Lincoln
Reply:Silane ? ! ?This is interesting : "At room temperature, silane is a gas, and is pyrophoric — it undergoes spontaneous combustion in air, without the need for external ignition.[4] However, the difficulties in explaining the available (often contradictory) combustion data are ascribed to the fact that silane itself is stable and that the natural formation of larger silanes during production, as well as the sensitivity of combustion to impurities such as moisture and to the catalytic effects of container surfaces causes its pyrophoricity.[5][6] Above 420 °C, silane decomposes into silicon and hydrogen; it can therefore be used in the chemical vapor deposition of silicon. Silane has a repulsive smell.[7]" From Wikipedia.com""The semiconductor industry used about 300 metric tons per year of silane in the late 1990s.[6] More recently, a growth in low-cost solar panel manufacturing has led to substantial consumption of silane for depositing amorphous silicon on glass and other surfaces.Silane is also used in supersonic combustion ramjets to initiate combustion in the compressed air stream. As it can burn using carbon dioxide as an oxidizer it is a candidate fuel for engines operating on Mars.[10] """A number of fatal industrial accidents produced by detonation and combustion of leaked silane in air have been reported.[12][13][14] Diluted silane mixtures with inert gases such as nitrogen or argon are even more likely to ignite when leaked into open air, compared to pure silane: even a 1% mixture of silane in pure nitrogen easily ignites when exposed to air.[15] Unlike methane, silane is fairly toxic: the lethal concentration in air for rats (LC50) is 0.96% (9600 ppm) over a 4-hour exposure. In addition, contact with eyes may form silicic acid with resultant irritation.""

Reply:If the gas is in a bottle, there must be a way to get it out in a controlled manner, so there must be a regulator available for it. possibly try contacting the major regulator manufactures and see if they have a product that will fit your application. I would think a regulator designed to have a fixed output would be a specialty item.

Reply:Silane ! Never heard of it before. Sounds like it would make some dandy liquid rocket fuel though !Robert Goddard move over ! Interesting on its use in ramjets. I remember that ramjets have a very difficult time because there is so little time for the fuel to burn. Have to research silane ! Going to try taking the tilt valve off the baloon inflator and put on a 10 psi LP reg. If that performs OK I will see if one of the Big compannies cah supply them that way from the factory.T |
