Method Exit bag and inert gas megathread

[Jdieiejdjaow]

Math isn't my strong suit today.

80cf tank of argon. 110 bars of pressure. Right around 1700 psi.

How many liters of gas do I have left.

Sorry for the pop math quiz

2,265 l

Though, I might be wrong. So feel free to correct me (someone).
Can you believe that for a ~€4 hose barb (12mm to 3/8") they charge €50 delivery fee inside the EU?

Well, since there is 28.31 liters for each cubic foot, that would be 2264 liters left at 80 cu ft, but original PSI could be 2200, and you have 1700, so you have 77% of tank left, which would leave you with 1743 liters left, way more than enough to CTB--At 25 lpm, that's roughly 70 minutes, and ten minutes is usually enough

Sorry for the pop math quiz

I have a 125 cu ft tank, 3540 liters, and even after three years, the PSI is still at 1600, so I have about 103 minutes left in the tank at 25 lpm, enough to CTB ten times over

Hello everyone!
English is not my native language, I use a translator, so I apologize in advance for inaccurate wording or terms. I will be glad if I am corrected if necessary.
I have been reading various topics here for quite a long time, I think I have figured it out enough to ask the right questions, or even help someone.
I chose the N2 method (SCBA or SCUBA) for myself. I live in Eastern Europe. I started by looking for a cylinder and N2 <-> AIR adapters. In my country, there are at least 3 suppliers of cylinder gas, I wrote a request to each of them. So far, I have received complete information only from one, but nuances have already appeared. This gas supplier seems to be a German company, and I think they can be trusted. They claim that all their gas is at least 99.995% pure. At the same time, there are also options of 99.999% and 99.9999%. But cylinders come with different types of connections: DIN 477-9 or DIN 477-10, depending on the cylinder volume and gas type. And it is necessary to properly choose the adapter N2 <-> AIR, according to the connection on the cylinder, to connect SCBA or SCUBA equipment. It will be either DIN 477-9 G 3/4 <-> G 5/8, or DIN 477-10 W24.32x1/14 <-> G 5/8. At the moment, both adapters are available for ordering online in EU, and I ordered both. By the way, in the description of the DIN 477-9 G 3/4 adapter it is written that it is for oxygen, probably this connection is "originally" used for O2.
DIN 477-9 G 3/4 – 5 l (99.995%), 10 l (99.995%) cylinders.
DIN 477-10 W24.32x1/14 - 8 l (99.995%), 10 l (99.999% and 99.9999%) cylinders.

I hope this will be useful to someone. If so, I will describe the further stages of the installation later.

What's the point of ordering a hose barb? It's a basic part that's used in all countries. You can buy it at your local hardware store for the same 4e or so. It's not a gas-specific part, these hose barb are used everywhere for water. And you need a gasket, of course.

And one more "life hack." If you need to connect two hoses (for example, extend the hose to the EEBD), you don't have to measure anything at all. Cut a 3 cm piece (1 minimum) from each hose and take it with you to the hardware store. Show them to the seller, and he will give you the right hose barb and hose clamps to connect one to the other.

I'm new to this website. How do I obtain a nitrogen tank in Australia? Any help would be greatly appreciated.

You'd be surprised to find out the little amount of welding equipment they've in Ireland. I've to buy most of the equipment from the UK or other countries in the EU.

There was a newer thread started by a woman i do believe about exit bag and inert gasses. It was started since this got so big.

Does anyone have the link for it.

That's the point of my message. You don't need a special welding shop to buy a hose barb like the one in the picture you posted, or any other hoses and fittings that are installed after the pressure regulator. All of this is available at a regular hardware store that sells various water pipes and fittings. I don't know what the correct English word is: hardware store, building store, or something else. A store that sells everything for building and repairing a house (paint, tools, garden hoses, etc.).

Actually, it's hard to find a female M12x1 hose barb → 3/8"

 

[Jdieiejdjaow]

Argon flow meter arrived. It comes with a hose barb already. The diameter I measured it (inner portion of the outlet) to be 0.50cm. Which is not 3/8". Did I measure correctly? I measured the bottom of the barb where the exhaust is (outlet). What is a fraction for inches that results in 0.50cm? I'm afraid I'll have to find a double sided barb with different sizes for each side as I'm pretty sure the eebd hose will be something different (. maybe 3/8"?).

LE: 3/16" seems to match. It converts to 0.47625cm. according to a table this means the outer diameter is 5/16" which translates as slightly less than 3/8" when converted to cm. definitely the eebd hose inner diameter will be bigger than this - should I be worried that I might get a leak if I use a 3/8" inner diameter hose with hose clamps on the flow meter hose barb? Assuming the eebd hose is 3/8"

LLE: with a hose of 5/16" to match flow meter barb, and, with a 8mm double sided barb, the eebd hose (assuming 3/8" inner diameter) will be ~1.5mm larger than the double sided hose barb side facing the eebd. If I use a hose clamp, should I be worried about leaks?

 

[Argonus]

Is the Green EEBD hood supposed to have spring tensioned exhale valve? At least onces I have it is just rubber flap. Putting gas in the hood simply pushes the exhale valve open emptying the hood of gas. I ordered SCBA mask to be sure, but still have the EEBD masks too.

Most eebd hoods have exhale valve to purge CO2. This is what you want. Inert gas in, CO2 out.

Bump. Any thoughts on this, folks?

LE: what are the downsides of choosing a hose barb bigger (with 2 and 0.5mm) than the hoses? I'm thinking this way the hoses will be more secure but I fear rupture or not fitting on the hose barb in the first place. Any suggestions?

 

[pappapgold]

I know everyone is against oxygen mask.
What if you used it along with the exit bag.

Insert the oxygen tube to the end of the lube going into the bag then open a hole in the side of tube from the tank.

You'll still get the pressure to the bag but you'll also get some of the gas straight to your face. It would in theory keep co2 away from coming back in.

Any advice is welcome
Just a mock up to see how it would go together

Im not sure at all, but with mine, the hose barb measurement was the widest (base) part of the barb. Which in my case was 1/4in. Then I got 1/4in ID hose which has an OD of 3/8in. I also got 1/4in hose clamp to make sure it's tight although that's prob more than I needed. The hose was so tight I couldn't budge it once I got it on. I don't think you'd be able to get the hose on with a larger barb.

Are you using an eebd or going with an exit bag?

 

[zardofan]

Bag. I purchased an Allegro hood but got worried about the connections. I'm also on the forums you can access when you buy PPEH. I felt reassured that I'll succeed with just bag versus possibility of leaks at the hood's connection points. Between here and there I've learned SO much. I appreciate the generosity of people sharing their knowledge!

 

[HouseofMortok]

Found a kit, comes with this regulator, but I'm struggling to convert bar/psi to lpm. Not sure if online calucators are correct. What would I set it on, on this regulator for 20 lpm?

The bottle holds 1200 litres. Which at 20 lpm should be 60 minutes run time.

It's this kit vs buying 4x 220L disposables and x4 regulators.

Thanks

There's no way to convert psi/bar to LPM. You'll have to buy a separate flow meter if you can't get the tank alone. A flow meter shows LPM in its reading. If you can't find one for N2 you might have to go with argon and use the table in this thread to convert to nitrogen.

From previous calculations, nitrogen LPM on the left is LPM argon reading on the right:

1.19 x 15lpm = 17.85 argon LPM reading
1.19 x 25lpm = 29.75 argon LPM reading

Do you have a measurement for the EEBD hose? Inner & outer diameter

There are hose barb that are dual

This particular one is 5/16" to 1/2"

Good to know this information. I can try looking for barb connections.
Or any information on the diameter of the quick connect that comes with this particular hood




Edit: the plug above is part number 9700-73B plug OBAC.......from a search, it shows up as being 1/4"

Thank you, found an Argon one, same litres, but the regulator for that is in lpm, which I can use your calculation.

I found a double sided hose barb that'll fit my hoses if the eebd proves to be what I think the id will be.

Be careful if you're using argon as your inert gas of choice. Usually it's not pure enough to transition with. I might be wrong, though I'd go with nitrogen (oxygen free) and use argon flow meter on the tank alongside table for calculations. Note that fittings might be harder to achieve with this setup if you use eebd/scba/elsa

When you find out the size, if you can please post.
Good information for others so they don't have to hunt & find fittings.

So basically. You'll need to buy the 40cfm tank, buy a regulator that screws on to the tank, and then get a long enough hose, turkey roasting bag and a drawcord. And then you're set.

Yep. And the hose barb to connect regulator to hose, and possibly an hose clamp (flat head screwdriver needed) to clamp hose onto the barb. Maybe some regulators come with the barb, mine did not.

And the toggles for the draw cord. And if you don't own a wrench, get one, finger tightening the regulator isn't enough. And do the math if you have to convert anything.

And then, as you say, you're set.
