At low P and T, yes, it does behave according to ideal gas laws.
At higher P and T, like 100psi and 100s of degrees C, it deviates from ideal. I think a bigger issue with using air is not so much the unideal expansion, but the combustibility of the compressed oxygen in air. There's a reason you avoid compressing gaseous oxygen. |

Yeah, that is my understanding as well.

O2 isn't combustible. Regular air is 78% nitrogen. 21% Oxygen and trace gases.
Take a look at someone who has popped out pipes. 30 psi isn't much, only 3 atm. |

Still incredibly dangerous stuff. You would probably get away with air, as the nitrogen would act as a suppressant, but using nitrogen instead of air is certainly safer. 30psi gauge is 2 atmospheres. There was mention of 80-100psi earlier in the thread. |

Never see it done at 100psi. The main danger you would have at 100 psi would be the pipe blowing up in your face when heated cherry red. You are not going to get a fireball or anything. Just metal blowing up in your face.
30psi is 3 atm as most gauges measure from one. 3 on the inside pushing against one from the outside. Guess we can argue that. Quote:

My experience ist not the air pressure is the secret to remove the dent, it's this heat. I always used the normal small gas lamps like in the video with no good results. Last time I used a butane burner which gives much more heat and a larger area of heating. It works much better and easier to remove the dents.

Got word that Brett with BonJoesCycleSport would be at the Little Brown Jug AMA national enduro this past weekend. So I took my 2 worst pipes. One was almost flattened at the largest diameter.
Report; nice guy. Professional. Did an unbelievable recovery on very bad pipes at a great price. Absolutely recommend. 716-773-5800 http://www.bonjoescyclesportinc.com Or you can continue to screw around in your garage and put your eye out while leaving ripples and dents.
