leakage or explosion pressure
leakage or explosion pressure
(OP)
steel pressure pipes : can you tell me, in case of failure, wich is the pressure for leakage and wich one for explosion ?
is there any difference between gas and liquid ?
This is just for my information (in fact I am working with potable water concrete pressure pipes) : I just need a flat answer (flat as much as possible)
Thanks

RE: leakage or explosion pressure
Gas has a greater, though much lower nowadays, potential for a running ductile fracture which could literally unzip a pipeline. Look up running ductile fracture to see what I mean.
If you want to go much further you need to study fracture mechanics of pipes. Most of these assume some sort of weakness, a crack, gouge or loss of wall thickness due to corrosion.

Also: There's usually a good reason why everyone does it that way
RE: leakage or explosion pressure
This is for steel, I don't know about other materials in the same depth.
Hope it helps.

RE: leakage or explosion pressure
As to the explosive or self-excavating nature of some such brittle concrete pressure and other brittle pipe material failures, a reading of the document at http://www.wsscwater.com/file/EngAndConst/80footse... may be of interest to you, and particularly when it get into the discussion of 80 feet "set-back" and 200 feet "debris throw" figures etc. from pages 5-6 or so on.
Even ductile materials can experience brittle fracture under some circumstances as others have noted, but not generally in the modern age of the spectacular nature seen by brittle materials such as what you are dealing with, pvc, and gray cast iron etc.
