Pressure Rise From Hydrostatic Piping Conditions 1

[lastone]

Could any of you please tell me where I can obtain data on the expected pressure rise in a liquid filled pipe under a hydro-static condition that is exposed to a heat flux?

In other words, if I have a blocked in pipe full of hydrocarbon, and this hydrocarbon is heated 40 degrees F, what is the expected pressure rise?

+40F? Won't be much of a pressure rise after the pipe fails. An oft quoted rule of thumb is 100 psi increase for each degree F. +40F is adding 4,000 psi. Generally enough to split the pipe in most applications.

OK, thank you David. That is what I thought, so I had them drain the pipe yesterday. I was just making sure. That wouldn't be Muleshoe TX you are referring to by any chance?

No, the company is named after a particularly interesting scale build-up on a half-muleshoe fitting downhole on a coal well.
