Pressure Rise From Hydrostatic Piping Conditions

Pressure Rise From Hydrostatic Piping Conditions

Pressure Rise From Hydrostatic Piping Conditions

(OP)
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?

RE: Pressure Rise From Hydrostatic Piping Conditions

+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.

(OP)
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?

RE: Pressure Rise From Hydrostatic Piping Conditions

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