Old acetelyne tank

[aczlan]

Bolted top plates are a standard feature. That is how they get the acetylene absorbent into the cylinder.

My suspection was correct, those are NOT bolts to hold the top plates on (not enough of them and they appear to be hollow with a lead core), they are relief plugs:

did they say WHY they won't take it for refill or exchange??. I've heard of that if another company has their stamp on it, identifying it as the property of that company, but without that stamp, it's a COC(customer owned cylinder) and gets refilled or exchanged. note that I'm not aware of any other place besides Praxair that refills Acetylene tanks, since it's so dangerous to do that!..

Try a different supplier. Replacing valves are a common thing. I just had to pay for replacing an O2 cylinder valve that was damaged. Don't ask the price, I did not even look at it as it was included in a $300 order of several tings.

Old Acetylene tanks went through some sort of regulation 10-15 yers ago. I'm not sure what it involved but I remember Praxair selling hundreds of old WS Avetylene tanks to some Mexico company for just above scrap price to not have to re-certify them. They paid a big fine for it.

Boy, i am glad somebody figured out tanks arent bolted together! There's a disaster in the making!

Tanks are welded together. The porous mass is sort of pumped in on a vibrating table when it is mfg. Acetone is the liquid that acetylene is dissolved in. Swapping valves on an acetylene tanks is a ***** and involves a bit of danger. The tanks need to be empty to revalve anyway. Best not to monkey around with the things. I have seen the autopsy photos and damage from the "jobs gone wrong".

CGA 300 is still used in some places to keep cylinder fleets captive. Theres an obsolete british thread that looks like that too.
