Question on nitrogen bottle

admin

I acquired a nitrogen bottle in a trade but it is bigger than I need. It is a air liquide bottle and is stamped DOT 3AA6000 on the side. I am having a hard time figuring out the volume and pressure. This bottle is bigger than I need and I would like to either a: trade it in for 2 80cf bottles if a gas supply house would do that orb: sell it for whatever it is worth and buy a couple bottles more along the sizes I need.What do you guys suggest?
Reply:I traded a couple lease bottles for credit towards 2 owner bottles.  I ended up paying 85$ with trade of a 140cf acetylene bottle for 80cf 75/25 ar-co2.  and 80$ with trade of 300cf oxygen bottle for pure argon. I would think that nitrogen is fairly easy to collect and bottle so you might get more than you think.

Reply:Pressure is 6000 psi.You may be giving them their bottle back if you can't prove ownership (i assume the collar has their name on it).Can't tell you anything about capacity without measurements.GravelThe difference between theory and practice is that in theory there is no difference.
Reply:So if the collar has a name on it that means it is a leased bottle? I thought it was just the manufacturer of the bottle.
Reply:Name on the collar may or may not be the owner of the cylinder. Many times companies change all the collars on exchange cylinders over to ones with their name on it. Other places keep customer owned cylinders seperate from rental/lease cylinders. Depends on who you are dealing with..No government ever voluntarily reduces itself in size.
