Currently in the process of re-design the studio for beadFX - where I teach - as they are moving to a new location - which is one of the reasons I've been very quiet lately. (The other has to do with my mother being ill - but that's another story.)
So - trying to figure out how big a gas line we need. We're going with Natural Gas (again) - and I got the following figures from Peter at Nortel Mfg - so I thought I would publish them here - in case someone else needs them, or I need them at some point in the future.
For Natural Gas
Mega & Minor Torch - at 1/4 psi, uses 3 litres per minute
Midrange Torch - at 1/4 psi, uses 8 litres per minute
Usage increases with psi increase - possibly up to 50% more.
BTUs - calculate at 35 btus/litre.
This is the info I fed to the gasfitter - got it straight from Peter.
Just don't ask me to explain it! ;-)
Oh thank you so much, it is very interesting ! (as usual...).
ReplyDeleteBut when i read Minor torch (which is mine), uses 3 litres per minute, it is not what is said in books. 5 litres is more usual no ?
Don't you believe that if i use 3 litres, my oxy concentrator will explode ?
When you said natural gas, do you mean "butane" or "propane" ?
Thank you for your answer, and sorry for my bad english...
Have a nice day,
Veronique (in France)
I will confirm with Peter - but you can use MORE than 3 lpm.
ReplyDeleteNo - I don't believe your concentrator will explode.
You don't happen to remember where you saw the reference to 5 lpm, do you?
Natural gas - see my article when it posts tonight.
