here is a link that should help you since you are obviously tryng to learn about pipe pressures and different pipes.

Deflagration to Detonation Transition.
Bad if your a average spudder, good if you have one helluva strong chamber and want to break the sound barrier.
More or less the shockwave from the flame front travelling faster then the speed of sound is too strong for the pipe to handle and it fails.... I think.

So I guess that means, don't have too long of a chamber (like a few meters long.)On the other hand, after a small spark has created a deflagration, the transition process can take several meters or longer and a corresponding large amount of time. The key to detonation initiation schemes applicable topulse detonation engines is to significantly shorten the distance and time required for deflagration-to-deto-nation transition.
Deflagration-to-detonation transition is the general process by which a subsonic combustion wave(deflagration or flame) becomes a supersonic combustion wave (detonation

I'm not the best person to talk to about this, I more or less have picked it up from reading other posts, you need someone like BoilingLeadBath, DIY or SpudBlaster15
