I‘ve seen a lot of Videos of Pipe repair,with
Pressure Air and Heat - with Water and Ice or Pressure Washer.
I work in a big Machine engeneering Company and
had a lot to do with Hydraulikzylinders.
So why not try with Hydraulik Pressure.
Today i make the test and it works really good.
Was a Little bit nervous about the Pressure of 50 bar, but nothing explodes.

You can use very low air pressure (20 - 30psi and thats all you really need unless your trying to get out really small dents) with high heat in small areas to relieve dents and creases if you apply the heat in the right areas, which is easy enough to learn with a little experience. Seeing as you can apply focused heat on one area using air as your force medium you can (with practise) fully remove and dents without any sign of them ever being there. Using fluids you need to run much higher pressures to get a similar result as you are acting on the entire inner surface area which honestly negates the saftey factor...
The Shop
When using air I always monitored while heating as the air expands and pressure increases .... so you bleed some pressure off as needed. I used rubber expansion plugs and hose clamps for safety and 1 plug had a tire valve stem with a pressure gage on it.
The Dents move out at 10-15 Bar but i want to test what is Possible and go up to 50 Bar, with a big safety Distance.
At 50 Bar the pipe expands like a balloon but nothing explodes.
Anyway, seems like a good way to remove dents. I guess my only minor concern would be what do you do with the used fluid dirty with pipe carbon and how do you clean all the oil out of the pipe before putting it back on the bike? Almost seems like more hassle than it's worth.
Repair, Rebuilt and Cleaning so for me its easy.
You are right its a lot of work but here in Austria we have 6 Month Winter so i have enough Time
