Help Nitrogen tank, regulator and hose specifications for UK

[BeyondTheHorizon]

Hi guys. I know this is already a topic that's heavily discussed across the website, but I would really like to receive some help with the exit bag method. I've been reading quite a few threads on here, but unfortunately most people give very detailed help only for the US specifications of the canister and regulator required. For example, I've read that in the US the recommended cylinder sizes are 20 to 40 cubic feet, but all canisters I'm seeing available in UK use measurements like "47 litre at 200 bar" or "8.5 metre cubed" (this makes especially no sense, at that is like 210000 cubic feet).

I know I probably sound like I've been lazy with my research, but I really have been looking for quite a while and can't seem to find reliable info on exactly which UK specifications I should look for. I've bought "Final Exit" by Derek Humphry but he doesn't go into much detail regarding UK measurements either. I could also do with some specific options for regulators and if there are any types or sizes of hose I need to look out for.

I thank you all kindly for any help you can give me in advance. I'm determined to do this right the first time.

I just bought a tank that looked reasonably sized (most are, except for the miniature bottles) and a regulator and it happened to fit. If you buy it all from the UK it'll most likely just fit. No technicalities neccessary

Cheers for the quick reply! How much did the tank/regulator cost you roughly? and what size was the one you bought? I'm seeing some now that are as tall as a human being but I'm sure that's much too big. I'm currently browsing shopairproducts.co.uk, do you happen to know if that's a reliable website? It says they even deliver.

If this works as well as I expect it to, I will be CTB very soon.

did you have any trouble purchasing nitrogen here in the uk?
I've considered buying some online but I'm wary if they will ask what it's for or if they will even deliver to a personal address and not a business one.

thanks.

The tank was 9 litres if I remember right, it cost about £150. If you're looking at one for about £30 or less then it's a miniature bottle which is no good. Yeah one as tall as a person is total overkill. I only bought them on eBay so I don't know about shopairproducts I'm afraid!

It was Argon, I couldn't find nitrogen. I just went to eBay, no questions were asked

Thanks Jodes, I've found a couple of UK websites now and BOC and ShopAirProducts seem to be rated the highest. I'm finding 30L technical grade nitrogen cylinders for around £40, any idea why they might be so cheap? Also, how much did your regulator cost? If you're planning on using your bottle soon I wish you the best of luck. See you on the other side, if it exists.

@lebrodude to answer your question they seem to be lenient with delivering to home addresses, and also have store pick up options. I've found nothing online about any UK Nitrogen sales regulations. It's not a dangerous gas (unless you intend to use it the way we do) so I doubt you'll have many issues. I'll be making an account and placing an order on one of those websites soon so I'll let you know how it goes.

I wonder if that 30 litres refers to expanded amount of gas rather than compressed, in which case it's a miniature. £40 seems too good to be true. I think I paid about £20 for the regulator but it was a while ago, I don't really remember

id really appreciate that , thanks.

im still really early in my planning with this method and have a lot of research to do, but it would be nice to attain the nitrogen and keep it in storage as a starting step.

Nitrogen is quite good for purging moisture from buried cables, in case anyone asks. Electrical or telecoms ones to be specific.

Not everyone looks like a welder.

I'm looking for exactly the same thing; can anyone confirm this is suitable? https://shopairproducts.co.uk/product.php?id=14620

That's indeed very cheap, maybe that's the price with some rental/contract involved?
Btw don't buy the 30L, that's too much, a 30L cylinder is super big and HEAVY.

Yep, that's a really good 5.0 cylinder.

what's 5.0?

 

[GasMonkey]

Purity rating.

 

[QuieterTimes]

Yeah, worked it out after I'd replied.

Hi GasMonkey,

Really appreciate the advice. I've just put in an order for the 10L cylinder you vouched for in this post. I've read elsewhere that it needs to run at 15LPM for a good 20 minutes, are you sure this one isn't too small? How do I convert and calculate how long this cylinder would keep "hissing"? Thanks again in advance. I should find out in 24 hours if they'll deliver it to me.

 

[GasMonkey]

10L * 200bar / 15 LPM = 133 minutes

Hi guys,

I tried to buy a bottle of Nitrogen yesterday. My story was that my dad was starting a beer-brewing venture and that my brother and I wanted to supply him with nitrogen and a regulator for Christmas. Unfortunately, my story fell through, as I had selected a "technical grade" nitrogen bottle over a "food grade" one.

My question is, is "food grade" nitrogen still useful to CTB? The company said they don't have anything below 30L cylinders for food grade, which is much too big and heavy obviously. If food grade is fine, I'll take my story to another vendor, and if not, does anyone have a good story to purchase "technical grade" nitrogen?

To clarify, they were willing to supply, but didn't have an appropriate size food-grade cylinder and I couldn't change my story to suit the technical grade stuff after I said it was for beer brewing.

Cheers,

BTH

And is this a good reg/flow meter for the cyl I linked to? https://staticarcwelding.co.uk/prod...-argon-mig-tig-welding?variant=33925385552003
