Let's say I'm bending some 1.5" steel pipe, or something along those lines. How much psi will I need if I'm using propane? I'm just wondering what sort of jobs an acetylene regulator that goes up to 15 psi can handle. For the most part I wouldn't be doing super heavy work.

Fuel gas regulator don't much care what you put through it from Hydrogen to Propane including Acetylene. Problem comes in when you crank on a regulator built for Acetylene to get past 15psi Propane loves on a large torch. Propane Air is a cost saving in heating jobs. Propane/Oxy is questionable unl...

from reading a few of these forums on this topic, it seemed people were saying that while technically you are supposed to change regulators, as long as you didn't need to exceed the psi on the acetylene regulator, you could still use it. what is the reason you were talking about for needing a differ...

I'm interested in using propane in my oxygen acetylene setup for the occasional heating or cutting work. If I'm interested in heating up 1/8" to 1/4" metal to bend, where can I find info on what size propane heating tip I would need? Also what propane psi range would I be using for that so...
