What size is this acetylene tank?

admin

I recently bought a used torch set via craigslist. Swapped the oxygen bottle today, turns out it 125 cu ft, yet i am unsure what size acetylene i have. The tank measures 39 inches high x 8.25 inches in diameter. Does anyone know what cubic foot volume this equates to? It also came with a victor 6-mfa rose bud, should i get a bigger tank to run this tip? Searching the web tells me it could be anywhere between 100 and 150 cubic feet, so no help there.

Reply:Originally Posted by DSWUnfortunately you won't find such an item. There are a number of companies making cylinders, and all are just a bit different. Also acetylene is stored in a porous material inside the cylinder and is dissolved in acetone. That means that unlike a "conventional" gas it's not as simple as a volume measurement.As far as other gasses like Argon, 75/25, O2 etc., unless you are working with metric cylinders that are done in liters, gas volumes are pressure related and the math is a bit "complex" for the average person. Total volume is based on cylinder size x rated pressure.I'll used my dive cylinders since I'm most familiar with working those numbers as examples.An 80cf 2400 psi cylinder is approximately the same physical size as a 100 cf 3500 psi  cylinder. A 2400 psi 104cf cylinder is much larger than the 3500 psi 100. An alum 100 cf cylinder is even larger, yet it holds 3500 psi because the cylinder walls are thicker. Physical dimensions of each size will also vary depending on who manufactured the cylinders, and sometimes they vary even from the same manufacturer, if the cylinders are a couple of years apart in age.From your description it sounds like you have a 75 cf acet cylinder. That's roughly the size my 2 are.

Reply:Anyone who can confirm the 130 cu mark means 130 cubic feet? I would normally make the assumption but i don't want to overdraw this tank.
