About 6.5kg.Anyone know how heavy 20L of Argon is at 200 bar?
What’s the advertised fill pressureJust picked up a 20L bottle. Supposed to be 200 bar I think?
Didn't feel very heavy.
There was a plastic shrinkwrap seal on it but no plastic screw in bung. Is that normal?
This is what I get.

That's a bit on the heavy side, STP is 0 Celsius it'll be slightly less dense at NTP (20 Celsius).About 7.14Kg I think.
20l x 200 = 4000l
1m^3 argon weighs 1.7838kg (@stp)
1m^3 = 1000l
4 x 1.7838 = 7.1352kg.
200 bar.What’s the advertised fill pressure
Avagadro’s hypotheses 1 mole occupies 22.4 litresAbout 7.14Kg I think.
20l x 200 = 4000l
1m^3 argon weighs 1.7838kg (@stp)
1m^3 = 1000l
4 x 1.7838 = 7.1352kg.
The ‘e’ is dropped from mole to indicate that we are now dealing with a gram of Argon, that’s the way we did at college.RonA: Should be 1 gram occupies ....... 0.564 litres.
1 gram mol is the same as mole, basically.
try a different reg first ,,, and try your reg on something you know has a set pressure in it .
Ideally you want three regs and two bottles , that way you know the fault isnt your reg , or if you have a calibrated gauge try that , a lot of divers have a decent gauge on a decanting whip if they blend gasses , and will have a bull nose adaptor too ..
some one elses welder would be the quick fix , they will have a bottle and gauge set . Local engineering shop and take them a bag of buns or the likes , two mins will check ... again just thinking out loud.
and if its not you look like a right ar*e ,, I like to know the answers before I ask the questions.simpler to just put the reg on the new bottle when you change it at their place, if it's 200 then job done, keep things simple....
....If you reg is out of date (look for the date on it) then they may not be prepared to accept the reading
I have all of the above ,,,, with the exception of the box of buns ,,,, they seem to keep vanishing.True there's that, but not the end of the world,
if you know your own kit, you'll pretty much know if it's working or not, even if it's a bit out (quite common) it shouldn't be reading less than 1/3 of the total.
Either way, looking an erse or not, it would prove the reg too, in any case I certainly wouldn't be faffing about trying to find a divers reg, someone with a set of calibrated regs or going round engineering shops / other suppliers with a box of buns to prove a welding bottle reg.... but each to their own eh.....
