Fire extinguisher wall thickness
I placing my bets for thsi question on the fact that we all come from different job or have messed about in the garage in the past
Does anyone know the wall thickness of a 9L/2Gal fire extinguisher?
They look like the perfect ends to an exhaust!!!

Never cut one open but this gives a range of values from 0.8mm to 5.5mm!

so i therefore think it depends on the type / what it contains / who made it.

I think you'll find that it's mostly the extinguishant that adds the most weight, that and the pressure vessel in the centre of some. But
as they are a £5 each for old ones on the Bay.

Nope. They can be Ali, Mild Steel or Stainless depending on make and finish.

It's been a while since I serviced one.
From memory, I would say around 1.5 to 2mm for a steel one.
Be careful taking them apart - there are two types
Gas Cartridge
and
Stored Pressure
The stored pressure ones have an external gauge, just ensure it reading zero before you open it.
The gas catridge ones, as the name suggests has an internal CO2 cartridge that is pierced as the handle is pushed down, thus pressurising the
extinguisher - you should be safe unscrewing one of these providing that no one has partially discharged it - keep your head clear of the top of both
types when dissasembling just in case.
They're charged to 10 Bar so be careful.

I cut one up to make a fuel tank for a static engine.
It was steel and <1mm thick.
If its a dry powder one dont try and flush it down a sink

Cheers Liam, but I'll just pull rank on the firemen at work, they'll have the spec sheets.

I UT'd all the different water types we have here and the bodies of all the 9l ones were 1.8mm plus or minus 0.1mm. Though the welded cap was
thicker at 2.4mm
There was also a one piece swaged type Co2 one here that was much thicker at 6.4mm.
