Has anyone got a 70mm x 6mm pitch threaded barrel bung I could have?
I have a 200 litre plastic barrel with two entry ports, a 2" BSP and a
70mm x 6 mm pitch, but the later is missing and I want to pump the
antifreeze from my furnance and chiller into it for transport..
Nice one, but the induction furnace has copper current carrying coils
with 10's of thousands of amps circulating. To keep the coil from
melting, chilled water is pumped round at a great rate of knots.
Freezing of the water would result in a total write off of the
equipment, so it is dosed with pure ethylene glycol (unlike car
antifreeze which has additives that would cause other problems. Total
system volume is such that I've got over £100 worth of glycol in
there, so don't want to just ditch it when moving, which would be
environmentally unfriendly anyway.
Still need that 70mm x 6mm pitch blue barrel bung though :(
...and cant spare it, as the barrel is full.
Ive advertised on the free-cycle groups for more 5 gal
barrels .......I need 20
as i have over 100 1 gallon containers to transfer over to 5 gallon
if i get 20 .i can spare this bung ...no answers so far .
anyway ...if its the same, picture will contribute to your cause .
all the best....mark
Yes it is surplus.
But if you ask me I don't really know if its meant for furnace work ..
If it was meant for extreme heat you would maybe have to wear an inner
insulated balaclava type thing
It's a strange one... maybe meant for microwave radiation.
Has fine wire mesh woven into what looks like glassfibre or poly outer
The same wiremesh is laminated into the visor....which is something
like 1/2 inch thick solid dense perspex looking stuff
Any-hows if interested give me a shout when your house move is done
and you are back in operation.
Was going to put it on ebay .....but not seen anything like it on
there .......and cant think of a way to describe it, so that people
looking for that specific type of helmet would find it ......as it
has no makers name on it.
Looks sort of like an airport firefighters helmet or a F1 pit-crew
all the best....mark
I'm afraid all I could find today were 45gallon oil drum bungs and some much
larger ones used with the 1 cubic metre plastic barrels for edm waste.
Would it be worth casting one out of a bit of tinplate for a body and a
canister of silicone or windscreen rubber for the sealing?
