O2 cleaning tanks

[pescador775]

I've never looked at a new Worthington or Asahi but Faber, Heiser and PST were/are O2 clean from the factory. My guess is that Mike's brew of tumble media and soap is causing a chemical reaction in the Worthington resulting in the nasty stuff. There are other possibilities but the likelihood of oil residue is remote, IMO. Steel tanks that I've cited are cleaned at the factory to remove oil residue. That stuff is not recommended for breathing air and the mfgrs are very cautious in supplying clean tanks.

Thirty minutes to clean a valve is pretty good for soap. I can't remove silicone from my hands in less than thirty minutes with soap. Using leftover ENSOLV, I can place valve components which are choked with silicone in a coffe can and remove same within five minutes sparkling clean in every nook and cranny.

I don't remember ever mentioning soap???

And it's not a brew, it is the proper measured amount of Ceramic media with Global 42100.

there is no chemical reaction that is causing the dirt to be there. Fabers are pretty good, but worthingtons need cleaning.

Also I don't place my components in a "coffee can" I place them in an industrial ultrasonic bath.

Let me know if you need me to clear anything else up for you.

Cheers.

Specially Worthington cylinders! I can take a brand new tank, tumble it for 3 hours, then upon draining the cleaning media and fluid is BLACK! really nasty stuff.

Mike.... my 2 Worthingtons were just filthy brand new from the factory....those did take a bit more elbow grease to get to O2 standards when I did them,,,I have heard from several others the same story....beware!

At any rate, make sure you fill your o2 slowly (about 70 to 80 cfm) and always open your DECO bottle VERY SLOWLY! that should keep you out of trouble... maybe

So you're saying to jam an AL80 full of oxygen in one minute. That's a little reckless for someone so anal about cleaning...

Maybe you got the fill rate mixed up? 70 to 80 psi per min is about 2 cfm or half an hour to fill an AL80.

add simple green, gravel, and some water.....force, uh, ask kids to roll across carpet for 1/2 hour, drain, rinse, check with black light, good to go......for cylinder anyways...

60 psi per minute is recommended fill rate for O2 I believe........

WOW!! Sorry about that... I was working on my Cuda's carburetor today and had CFM on my mind..

What I really wanted to say was "70 to a max of 100 psi per minute". Those are the IANTD specs.

Thank you very much for pointing that out. I will now go DECO on my couch with a cold one

Cheers

Mike, that Global stuff is interchangeable with many other so called degreasers such as Simple Green Crystal and mama's citrus floor cleaner. Global changed to that cleaner because the mfgr discontinued the other, green stuff. It is soap and that is why tumbling is required. If the Worthingtons are "dirty" then they should be cleaned. My guess is that the "dirt" is residue from a phosphate wash which is not exactly threatening. However, contacting Worthington may or may not elicit a correct answer so it may not be worth the trouble. On the other hand, curiosity may get the upper hand. Kudos for you on the industrial whatis. I skipped that and went to better living through chemistry.

I call that my HYBRID tumbler

Sigh... Why does Worthington have so many issues unlike we didn't hear from PST.

I neve doubt their cleanness of the brand new tank directly from the factory.
