I think I've blown off

[Paul G]

Hi All.

All was quiet in the workshop, hot but quiet, when a loud whoosh was heard.
I rushed in to find my spare bottle of pub gas expelling it's contents from the safety valve hole. (arrowed in pic)

In all my years of welding I've never seen one blow before.
Huh! Another £15 down the drain.


Cheers,
Paul G

I should think if you take the photo as proof any decent supplier would replace FOC.

 

[Shox Dr]

Bizzare, ^I'd do the same

 

[Paul G]

No no chaps; its not the money.
I wouldn't expect the landlord to cough up when he is kind enough to supply me with gas. It's not his fault.

It's more curiosity really.
Has anyone known one to blow before?
It was 30deg C (in the shade) but they should withstand that I would have thought.

Cheers,
Paul G

Yep I was in rhodes greece 2yrs ago when I went for a quiet walk on my own i was fed up with wife moanin ( not in a good way !!) and the sisters kids screamin and arguing so I went for a walk round the outside perimeter ended up by the bar back door where there was a few co2's stood against the wall with the sun beating down on them, it was silent there just the insects buzing etc and I was in aworld of my own just strollin my mind far from welding and cars etc , as I got right by the cyl's one let go, I am not nervous normally and take everything in my stride but I nearly sh*t, you sort of expect things in a workshop enviroment but it was the last thing on my mind I nearly ended up havin another heart attack !!!
it was just about as hot as a few days ago so it IS the heat I spoke with the barman Janis that night and he said it was a regular thing, if their left stood in the sun they should have been moved into the shed.

CO2 cylinders will vent off in high temperatures

if there out in the sun in the kind of heat we've had the last few days they will vent.

C02 is liquid in the bottels so if it gets hot as more trys to turn to gas the pressure rises lot so they have to vent

The burst disc popping when the weather warmed up was a common occurrance when using Co2 for paintball if the weights were not checked when filling and I know of one team that would quite happily fit two burst discs so they could overfill their cylinders.
One of their guys had an overfilled 20oz bottle that burst open under his bed sending shrapnel through the mattress injuring him. Another had an overfilled cylinder pop the burst disc inside his car on the motorway filling the car instantly with Co2 mist! Luckily the motorway was empty and he managed to get the window open and his head out to follow the white line then pull over to change his undies.

Though paintballin was supposed to be a 'safe' pastime !!
an gettin shrapnel in your **** was for real soldiers

You would think so but the last big game I attended the organiser injured hiself letting off pyros! Back in the early 90s I was in control of our teams bottle filling station and Co2 bottle because it was on my BOC account. I engraved all the team cylinders with full & empty weights and we had no problems. Nowadays it's mostly compressed air (dive tank pressures) and the sites supply the air, the bottle safety is tighter too.
