So I have a 48/3000 steel tank and I need to remove the regulator due to some how the threads for the tank getting wrecked, the only promblem is that right now there is about 1000 psi in the tank and I dont know a way of removing it. Does anyone have any ideas/ experince with this?

Hook up a remote line and tap the tank.  It'll just vent out the line.  Hold onto the end of the line.

 

Edit: threads are ruined...oops...  Can you thread anything on the tank at all?

The problem is the threads are damaged and nothing can be screwed on to it

 

 

Edit: Nothing can be hooked on to it without wrecking the threads of both

Or you can pop a burst disk.

We just press the pin on the corner of a table, Most of the sound gets directed downwards.


What?! I'm all out of powdered toast?!

Can you push down the pin against 1000PSI?


Or do the best you can of cleaning up the threads and scrrew it into a cheap ASA or remote line??

Or you can pop a burst disk.

 

The burst disk pops from the inside, and you can't take the disk off without it becoming a bullet.  I would not suggest trying.  The disks are also on the marker side of the reg, meaning its only going to max out (if everything is working correctly) around 850 psi.  You have two burst disks generally and ones a higher range, typically around 1.5-2 times the tank pressure and a lower disk, usually around 1.8k psi, both are way larger than the reg output.

If threads are destroyed the only things I would try:

 

Attempt to clean the threads and use a remote line like I said earlier or if the tank pressure is low enough to wear you can controllably press the reg pin and vent air manually you can do that.  Please wear eye protection if you manually press the pin.  Compressed air blown into your eyes can cause permanant damage, even at extremely low pressures.

you could buy a cheap $10 asa
but you also can press the pin down
its actually pretty easy, and you will only be pushing against 850 psi because that is what the pressure is regulated to
but if you try this, definitely wear ear, eye and hand protection

 

I'm also interested in learning about this - how do I properly degas my HPA tank?

you can drain it by hooking it up to a remote line and turning the remote on, you can push the pin down using a screw driver or allen wrench or something like that, or you can screw the tank into an asa of any kind

I just screw my tank into my marker, remove the macroline, and turn my ASA on. Then the air rushes out of the fitting and disperses into the open air. Then I close the ASA and put the macroline back in once the tank is empty.

Thanks for your help mate. So for example, I can screw my tank into a GEO 3.1, turn the button ASA on and just slowly unscrew the macroline?

 

(This is the the GEO's new trigger frame macroline)

just take the air transfer pipe off, then screw your tank in and turn on the asa
that'll drain your tank. it might be a little loud, but its the quickest and easiest way of doing it. 
if you were to try to unscrew the air transfer pipe while it was under pressure, first off i dont think you could actually get it undone, and second, you'd wreck your orings
