Help Exit Bag Inert Gas (NITROGEN) For UK users

[Blockz]

Hi guys im practically new here, I hope everyone is keeping well :D

I have read a few posts in regards to an exit bag inert method but i haven't found one for UK users specifically as i need links to what equipment is needed and how would one go about constructing the tubing, regulator to the gas tank and how to connect the tubing which is required to the exit bag, please dont post any links on the forum as this goes against the rules but please do message me privately i would appreciate it greatly

I think you'll have to post a few more times before anyone can message directly.
Have you researched this forum and internet? There is a lot of information to be attained.

YESSS i have, i have the PPH downloaded and saved onto my phone aswell as a way on how to construct the exit bag via video demonstration

Sounds like you have a good start.
The only other parts are the regulator, hoses & cylinder.
Cylinder probably needs to be at least 40cf or 1.1 m3.
Regulator is needed to reduce the pressure down to around 80-100 psi or 5.5 to 6.5 bar.

have you looked into finding helium?

No I have not could you post a few more times for me on different forums so we can speak privately

 

[Blockz]

Im not comfortable sending you my source. but as far as helium goes, a quick search online and you will easily find 99½ purity from the EU.

The ole Americans are all using nitrogen, as their helium has been watered down due to the popularity of all the suicides by helium over there.

If you think the UK is a bad place to live in, the USA can be a hell of a lot worse.
no NHS, no such thing as council housing, no such thing as a college grant.

in the UK every now and then you hear of some guy trying his hand
at a mass stabbing. in the us its a mass shooting.

what Mexico is to the Americans, America is to the Brits. lol

I mean if you think Rishi Sunak is something to worry about,
at least you don't have sleepy Alzheimer Joe running the country.

Honestly you made my day, you made laugh way too hard. Thing is everything you said is literal facts I know I asked you for your source but I think I should be able to find smth in regards to a helium tank, all I really need help with is the correct regulator, tubing and I'm wondering if you're down to make you're own exit bag in regards to the tank that I'll be able to find on my own but Thankyou honestly for getting back to me I'm looking to ctb asap but if we could partner up and you could help me in regards to a regulator/flowmeter I'd be honestly so grateful in regards to the tank I'll have a look around because I've just been looking for nitrogen at this point I'm also looking at SN and I have a source in regards to that if you're interested please lmk.

mate, if you can wait a month, id love to go together over a zoom call.
listening to shitty boyzone. :)

FYI i dont think you need a regulator for helium.
maybe start a new post and find out if im right on that.

and please if you need to go before me, at least wait until iv secured my helium.
i don't want to loose out on my chance of buying it because you got there before me.
as for my own exit bag, one of the books i read said to use an oven turkey bag. you get them in all the major supermarkets. look to the resources thread. the books are easy to come by.

Ngl I don't think you do need a regulator it's just that I've been looking a nitrogen tanks and regulators that I'm getting confused as to how it's different with helium, I've got the pph 2022 edition downloaded I've also got a source for you in regards to helium which I just managed to get by signing up to some kind of subscription I'd be defo down for a call, I was just thinking like if I'm able to secure everything asap I would ctb but if I can help someone else out then I'm defo working with you bro I'll send this mini source idk if it's of much help tho but everything helps in some way

One will need a regulator of some sort if a cylinder (tank) is used. The gas in those cylinders are pressurized to about 2200 psi or 150 bar.
Without it, one would have a hard time keeping the hood on and it would let the gas flow out very quickly. Most cylinders with compressed gas are made to have a regulator attached to them. I'm not sure if the balloon tanks in the brochure do or not....it might be specialized for filling balloons.

Helium cylinders typically use the same sort of regulator as any other inert gas (nitrogen, argon, etc).
PPH shows that In the UK, it appears that the 'BS341-No3' is the connection type. (See page 133/134 in the PPH 2023 edition for the setup & parts)

Parts:
Inert Gas Cylinder
Regulator (connected to cylinder)
Hose (from regulator output)
Hood (hose attached to inside of hood)

I am also in the uk and looking at this method for the next few weeks. Have you guys got any further? I am still unsure that the helium would be 100% even though it says it is. And also about buying and connecting the tubing securely.

I wouldn't trust 'helium for balloons' tank to be pure enough. But they use helium for welding as well. Search for 'helium technical'.

As for the tubing: one can buy a tubing used for oxygen at a pharmacy (online) or crystal pvc tubing and use this to connect it with the tank:

Thanks so much. What is that connector called please?

Also nitrogen regulators only come in PSI (pressure) which can't be converted to flow (LPM). Should I use an argon or helium regulator instead as they seem to show LPM. Or do I need to get a rotameter? And will the rota meter be enough on its own without a regulator (ie it can regulate too) or do I need both?

Regulator is needed to reduce the pressure down to around 80-100 psi or 5.5 to 6.5 bar.

This is a brilliant number, DA. Where did you get it? All the info here uses the oxygen number from Peaceful Pill of 15 LPM, which isn't a measure of nitrogen.

Sorry I can't remember where I saw this or if it was something I calculated myself.
I think this pressure amount has to to with what an equivalent of giving 15 liters per minute.
Or this was the pressure that the regulators work on a SCBA system.
Those inert cylinder tanks are pressurized to be about 2000 psi or 150 bar.
You need a regulator to bring that down into something more manageable....somewhere around 2-6 bar, I would think would work fine.
Pressure and flow depend on the area what it is flowing thru as well...which is variable.

BUT it seems many inert gas regulators have a flow gauge on them...either in liters or cubic feet per minute.
These also tend to operate at set pressure of 50 psi or about 3.4 bar.
So the pressure might not be something that can be adjusted.

15 liters per minute is the same as 35-40 cubic feet per hour. (there are several online calculators to figure this)

These regulators are mainly used for Argon gas, but they can be used for Nitrogen as well. Just that the flow Lpm is slightly different based on the gas density.
So I'd say a 15-25 Lpm should be good....also based on feel as well...some say 15 is too low.

So in the UK, I would say to look for a regulator that has a flow gauge on it like the one pictured above.
They are usually for Argon, but the connection should be the same for a nitrogen cylinder.
This particular regulator has a barbed end which allows one to put tubing on it & it should work fine.
The knob would finely adjust the flow. The steel ball in the glass container part will float & give a visual of the flow (in Lpm in this case).
I would say somewhere between 15-25.
