RE: tank O2 cleaning
Quote:
jameswirth (7/16/2008)Dude,
Just take the valve off, put some simple green in there.. wash it out a few times. Flush some of that through the valve too. Look in the tank, it should be clean.. no particles, scale, white powder from the AL,or anything. Now you're good to go. People get really homo on this O2 clean garbage. It is a way for dive shops to charge you more money every year. You know, there is no law that tanks have to be hydro'ed or VIP'ed every year. smoke, mirrors, more money out of your wallet, etc. If you do the above you're good forpartial pressure fill nitrox or pure O2.
If it is banked Nitrox, you could put it in a rusty tank half full of gasoline and you'd be fine...

As long as you don't put more than 500 psi of pure O2 into a tank before putting air into it you are fine. As for the hydro of a tank it MUST be hydroed at least every 5 years to be LEGAL its the law. As for the VIP you are correct but try and get a tank filled at a shop without a VIP it's an unwritten law so to speak. As for the homo about O2 here's what can happen if you have a dirty or contaminated line in the charging system of pure O2. Charge that cylinder with pure O2 very slow or it will make a very very big booming sound!!!
