Heat Emission from Pipes Submerged in Oil or Fat

Heat emission from steam or water heating pipes submerged in oil or fat - forced and natural circulation

The viscosity of a fluid has considerable influence on the heat transfered from a submerged heating pipe. Be aware that the viscosity of a fluid is highly dependent on the temperature.

Oil or fat tank - steam heating coil

Heat emission from steam pipes submerged in oil baths are indicated below:

ApplicationFluidHeat Emission from coil surface
 (Btu/ft2 hr oF)(W/m2 oC)
Steam coil with medium steam pressure and natural convection of oil Light Oils 30 170
Heavy Oils 15 - 20 85 - 115
Fats 5 - 10 30 - 60
Steam coil with medium pressure and forced convection of oil Light Oils 100 570
Heavy Oils 60 340
Fats 30 170
  • Light oils - 220 SSU at 100 oF
  • Heavy oils - 1100 SSU at 100 oF
  • Fats - 3833 SSU at 100 oF
