C-25 Transfill

[Kempy]

Understood, no worries. Inert / shielding gasses are one thing, oxygen a totally different deal. Couldn't even begin to imagine what an acetylene (liquid under pressure) would look like.

Acetylene pressure in a full tank is about 250 psi but it is put in a tank that is packed with balsa wood or monolithic material then filled with acetone or dimethylformanide (DMF) this is why the tank is so heavy the acetylene gas is absorbed in to the liquid under pressure. Acetylene gas under pressure at 29.4 psi, acetylene becomes self-explosive, and a slight shock will cause it to explode spontaneously. However, when dissolved in acetone or DMF, it can be compressed into cylinders at pressures up to 250 psi. safely.
