BaGearA Posted January 7, 2020 Share I think these canisters are used in other domestic and industrial applications so they should be made to an international standard. Ill sift through the IHS library and find it.the small 12/16 and 25 g ones ? obviously the bigger ones would be crazy regulated , but the smaller ones im doubtful Link to comment Share on other sites More sharing options...
Fat Boab Posted January 8, 2020 Share Look at the units of your pressure scale. Bar not psi... that assuming ideal conditions , the space in your tyre obviously has a big influence Link to comment Share on other sites More sharing options...

dave303e Posted January 8, 2020 Share Sorta related, what happens when a tubeless setup goes wrong: https://www.pinkbike.com/video/509984/ I did this at a petrol station...................With the bike in the back of my old BMW X1. Sold the car a few months later but to this day I reckon you could find some Stan's slime somewhere in that car if you looked hard enough. What you don't realise as well is that poor bugger has to get tyre slime out is eyes and nose and his ears will likely ring all day and that rim is likely ruined and merely an ornament now.

piotter Posted January 8, 2020 Share A couple of months ago I was pumping up my my tubeless tire in my garage. I'm pretty certain I wasn't pumping to any higher a pressure than normal, so think maybe it wasn't seated correctly, but... The bang when it unseated itself completely was pretty terrifying, and the amount of sealant spread all over the garage... duringd 1 Link to comment Share on other sites More sharing options...
scotty Posted January 8, 2020 Share Topped up sealant, pumped tyres , washed bike and left in sun to dry, go inside and while later I thought a bomb had gone off, mine and neighborhood dogs went ballistic. Spent next few hours removing sticky sealant from bike and paving. Long Wheel Base, Mokgaga'a mmakubela! and Wannabe 3 Link to comment Share on other sites More sharing options...

BaGearA Posted January 8, 2020 Share Look at the units of your pressure scale. Bar not psi... 5.1 bar = 75psi roughly What is your issue? Is the thought of liquid co2 so terrifying? Link to comment Share on other sites More sharing options...
BaGearA Posted January 8, 2020 Share Self inflating life jackets use similar, if not same, ones.Okay then I'm fairly certain they'd be regulated, so maybe bad luck since that little cap at the top must be thinner than the wall of the thing, no?

The Ouzo Posted January 8, 2020 Share Okay then I'm fairly certain they'd be regulated, so maybe bad luck since that little cap at the top must be thinner than the wall of the thing, no?my uneducated guess would that the aircraft grade ones are manufactured under tighter controls Link to comment Share on other sites More sharing options...
Jehosefat Posted January 8, 2020 Share 5.1 bar = 75psi roughly What is your issue? Is the thought of liquid co2 so terrifying? His point is that you seem to be reading the graphs incorrectly. At 32c the pressure has to be above 74 bar (1023psi) for CO2 to be liquid. At 5.1 bar the temperature has to be less than -56c for the CO2 to be liquid. So there will never be liquid CO2 in your tyres ever. Although there is very likely to be some liquid in the CO2 bombs. Link to comment Share on other sites More sharing options...

Fat Boab Posted January 8, 2020 Share Pretty much! Although some basic ideal gas law calcs suggests bombs contain only compressed gas. His point is that you seem to be reading the graphs incorrectly.

Please make sure you use blue sealant then the kids can at least play with a smurf afterwards piotter 1 Link to comment Share on other sites More sharing options...
