Carbon Fibre Bottles and filling them
Have heard there has been some report (which I am being sent) about the filling of Carbon Fibre bottles.
Carbon Fibre bottles have different heat characteristics to fibre wrapped bottles which makes them more prone to bottle fires (The bottle in Madrid was a carbon fibre bottle)
Have yet to see the recommendations on filling them, but have heard that a maximum of around 120 litres per minute for filling is recommended.
The only carbon fibre bottles that I am aware of are the Stako bottles.
I will make some ammendments to the UKPSF air fill policy which will read as follows until more information is forthcoming.
1) Advise all players that carbon fibre bottles have more of a risk when it comes to bottle fires.
2) Have a seperate fill point for carbon fibre bottles with a flow rate less than 120 litres per minute.
3) If no specific fill point is available, advise users of carbon fibre bottles, to fill in stages of 1000psi per stage. ie. fill to 1000psi, then stop and wait 60 seconds, fill to 2000psi and stop for 60 seconds, then fill to 3000psi.
It should also be remembered that flow rates for filling of any air bottle should be regulated. As a guide, it should take around 45 seconds to fill a 0.8L steel bottle from empty to 3000psi. In practice, sites usually top up from around 2000psi to 3000psi which only takes around 15 seconds.
If you have an unregulated fill rig (ie a dinn or A clamp fitted to a dive bottle), please be aware of the above. food for thought guys just read this on www.talkpaintball.co.uk
