Incredible welds

[loki]

Absolutely nothing wrong with DA as long as it's used and stored with care and respect. I work in the industry that makes DA and of course there can be incidents but more often than not, it's not just a cylinder that goes pop. Poor hoses, out of date and service flashback arrestors, Regulators used by Noah to weld part of the ark. Then you have the users who "think" they know how to store it as well as strip down their kit after use.


In this thread alone there are a great many myths that simply aren't true

Bizarre but

Sounds about right.

I've got a compressor in my garage and one regular bit pf maintenance that you have to do is to let the water drain from the tank every so often. I never remember to do it of course even though I know it's essential. The water can corrode the tank, leading to a weakness in the cylinder wall, and that's not good if you're then pressurising the thing!

So let me get this right, your taking the valve off the top off a cylinder and draining the water off the tank ????

Mine has a tap at the bottom of the tank, you just open it a bit and let the liquid squirt out.

The issue of the water corroding the cylinder wall is negligble. It would take a very long time for that to happen. By which you should have exchanged it anwyay. What's more worrying is that you are using a compressor on the cylinder. Trust me you are running a much bigger risk than anything water would do to the cylinder.

Acetylene is a highly flammable compound and could ignite and explode under any number of conditions.

Acetylene has a flammable range of 2.5% to 85% in air. This means that if an ignition source is present (such as a spark of static electricity or a match) acetylene will burn.

If there is less than 2.5% acetylene in the air, there is not enough to burn. If there is more than 85% in the air, there is not enough oxygen to support the burning (although acetylene can decompose if ignited, even without any oxygen).

Sorry Faysh, thats not correct, DA is lighter than air and will rise.

If anyone wants any safety information on DA or any compressed gases send me a PM and I will send you as much or as little safety info that you need.

Sorry if I misled you. When I talked of the cylinder, I meant the compressor's cylinder (the compressor consists of a motor and cylinder). I'm not using the compressor to fill any external cylinders

so has mine - I just haven't done it yet!
