I'm familiar with the Joule Thomson effect. A gas will cool when depressurized because of the expansion of the gas. I believe the expansion of hydraulic oil from pressurized to depressurized state is so little that JT effect can be safely ignored.
I used to use...

Trying to go from 70 to 240 just on pressure drop is possible.
GjFi is correct that it will take about 140 psi drop per deg F you want the oil temperature to rise. (I'm assuming .45 Btu/lb deg F heat capacity and a density of about .9 specific gravity, both pretty typical of...
I may be off base here, but being that you are looking at an application at the bottom of the sea, have you considered the effects of the water pressure in the lowering of the freezing point of the water? Perhaps such a consideration may be enough to prove that the piping will not ice in the...
I have got a rather oddball situation. I've got 316 SS tube, 3.5 OD, .5" wall that I am attempting to polish to 120 grit, then weld lengths together, and then bend into a 60" average diameter helical coil. I have some vendors lined up that say they can handle making such a coil, but...
