New 23 Litre Ball Lock Cornies FS

[airymary]

Hi Guys

I have a couple of these available, BNIAB. To extol their virtues, they're 304 s/s, and 60 psi, not the usual 40, giving a better margin for force carb'ing, and implying a heavier build quality. In use, I secondary ferment by just adding priming sugar - no need to force the lid to seal with CO2 (unlike used cornies). And, of course, they're very SHINY . Like this:



I see that THBS is out of their 40 psi ones, and other online HBSs price theirs at well over a ton. Mine are £85 to Forum members for collection (London E17). Delivery at cost. I'll soon be putting them on the 'Bay at a significantly higher price. Get 'em while they're hot!

Cheers,
Chris

Are these Chinese ones ?

I didn't realise they were 40 / 60 PSI - all mine are the older ones and IIRC rated at 120 PSI which I find useful, in the summer I have been known to fill unused ones with water and stick around 60 PSI on them.

Hi Hawks
The psi rating tends to coincide with the PRV's setting. I would expect that they've been destruction tested to at least double that, to arrive at a rating for day-to-day use.

Just one left now.

Cheers
Chris

Yeh mine are all 120 psi.

Why? How often do you need 120 psi for homebrew? Kegs now gone - last one went on Ebay at the aforementioned 'significantly higher price'. Bargain well and truly missed!

There is nothing like a good factor of saftey when it comes to pressurised vessles in your house :)

I was reading a post on an american homebrew website that analysed the pressure build up in bottles while they carbonated. I think if I remember correctly the pressure gauge he used on the bottle went beyond the maximum read out on his pressure gauges which was around 30 PSI.

Personally after reading that I would worry about using kegs with such low PSI ratings for doing any carbonation with priming sugar. CO2 bottle is probably fine.

EDIT: This wasn't the one but its the same type of thing : http://beertech.blogspot.co.uk/2009/12/ ... -test.html

Seems to me if your keg can only handle 40psi you are dangerously close to an issue ? at 60 psi I would imagine you have a reasonable safety margin.

No offense, but isn't this typical of the negativity directed at Chinese 'not proper' cornies?

Pressure barrels are rated as low as 10 psi. I'm confident that many thousands of homebrewers have primed brews in them over the decades without issues - I certainly have. If they need to be 4 to 6 times the manufacturer's rating, someone needs to have a word with Youngs, King Keg, Rotokeg, etc.

No, I don't believe you can make accurate comparisons between bulk secondary fermentation in a barrel or keg, and that which takes place within the confines of a bottle. To then draw conclusions from that about the differences between the original corny kegs and Chinese copies is, I believe, fallacious.

The original cornies were designed for the soft drinks industry, to move thick syrups over quite long distances from cellar to bar. That's why they're 120 psi, not for our benefit. The Chinese copies are for the homebrew user, and, at 40 or 60 psi, are entirely fit for purpose.

Rant over!

Cheers,
Chris

Chris, I'm not being negative, but, priming a pressure barrel with 120g of sugar will not cause issues because as you say the PRV lifts at 10 psi . . .this actually protects against over carbonation as well as being a safety issue. I can see no real issue with 'only' having a 40 or 60 psi rating on a corny . . . apart from natural conditioning where with the much higher pressure you will get over carbonated beer unless you get the priming exactly right . . . . because the PRV doesn't lift until a much higher pressure is achieved.

40, 60 or 120 psi is not really important unless you are producing soda water, and even there 40 psi is fine, but for some of the really highly carbonated beers then 40psi may be a little low unless you can get the beer cooled significantly.

As I said I don't think it's too important, especially as my reg PRV's blow at 60psi anyway . . . I was trying to use a corny as a emergency gas cylinder, and discovered that it wouldn't work . . It's about as important as a keg having a couple of minor dents and scratches . . .you can't see them when it'[s in the kegerator

Shrugs.... and no real need to rant... A conversation will do :)

I have no idea to be honest on the difference between the potential PSI in a bottle vs a keg. I only know what I posted and what concerns me about these lower rated kegs. Didn't even know about these kegs until I read this thread.

Just saying if I had a choice between the 130psi ones and the 40 / 60 psi ones, I would be going for the 130psi ones given what I know about the potential PSI in a bottle. Have you got any details on the potential PSI in a keg compared to a bottle?

I currently have three kegs in my house with children wandering around... I personally aint taking any chances and feel way more comfortable using a much higher rated keg. Others are free to do as they please.

Just remember that these ratings are the point at which the PRV 'valve' on the keg lifts. In this way the lower rated cornys are actually 'safer', although technically if you have a decent regulator it will have it's own PRV as well

Hi dx and Aleman

Can't fault you for prioritising safety with kids around. I ocassionally have children visiting (friends, family, lala), and genuinely don't believe I'm compromising their safety with my lower psi rated kegs. I also use a budget PB adapted as a keg, and attached to a pub cylinder. Only 10 psi! I turn the cylinder off when kids are visiting and the PB is connected. As you say "Others are free..."

Just remember that these ratings are the point at which the PRV 'valve' on the keg lifts. In this way the lower rated cornys are actually 'safer',

A helpful observation - cheers!

..although technically if you have a decent regulator it will have it's own PRV as well

I use a welding reg - tch tch :) I suppose that I have a concern about Chinese kegs not being imported due to low sales. It will leave us complaining that cornies of any sort are rich mens' toys - "...just of to buy a corny darling - shall I leave the Merc or the Bentley for you?"
Lol o 'el! :cry:
