Original Q&A about Nitrogen

Wow, I didn't know this.

Do not fill your HPA system with CO2. If it is a fiber wrapped tank the change in temp will cause the inner aluminum liner to expand and contract and by doing this seperating from the fiber wrap. This can cause the tank to fail. Also, most regs that are on HPA systems do not like liquid CO2.

Tom made that comment back when they were using steel hpa tanks, right? rather than the fiber wrapped aluminum...

[Muzikman]

More than likely. Steel was more common back then, but fiber wrapped was around.

well in another comment tom does say that it is the same fiber wrapped tanks used in space shuttles, and in an old pic that was on AO a little while ago tom and his team was using fiber wrapped tanks. (but i dont know when that pic was taken)

Dont think so. We were using 68 3000 carleton tanks for co2 all the time.[3yrs] Pin valve,no pin with on/off right on valve. Had to switch for the IAO

I am trying to find the article about doing so. It was also what I was told by the APPA years ago when they had a class about HPA.

It sounds logical, so I would rather play on the side of caution.

EDIT:
Not that it doesn't mean much, but Criag Palmer doesn't like the idea much either;

its all good

Hey I hear ya better Safe Then Dead, Hurt or Blind. If we knew then what we know now.eh Then again look at what we know now. It doesnt seem to be helping us any.
Just like now, we say what the hell were we thinking back then, they will look back to now and say the same thing.


Peace Out

Old wives tale about the tanks. I asked our tank manufacturers about this and it isn't a problem. :)

But very true that many tank regs aren't so compatible with CO2.

Good to know, still not gonna do it:) I got CO2 tanks if I want to run CO2.

Indeed.

I've had fiber wrapped CO2 tanks for years and years, with no problems.

And really, if the chill from CO2 would damage the resin bond, the heat from an HPA fill certainly would too.

I like that crack about global warming at the end, that was priceless.

Well the heat from a FLASH FILL does do damage to the tank.

Our semi-auto the 68AUTOMAG when custom tuned, has recorded chrono strings as fast as 9 shots per second. This blurs the distinction between semi and full-auto and is prompting the major tournament directors to consider limiting the number of semi-auto's per team.

My how times change......

Indeed, but only if it heats the tank in excess of 140 deg F.

Edited to reflect correct temp.
