The table below can be used when designing oil pipes:
|Oil Application||Oil Flow Velocity|
|Suction lines for pumps||< 0.5||< 1.6|
|Suction lines for pumps at low pressures||0.1 - 0.2||0.3 - 0.65|
|Discharge lines for booster pumps||1.0 - 2.0||3.3 - 6.5|
|Discharge lines for burner pumps||< 1.0||< 3.3|
Values depends on the viscosity of the oil - typical qualities like benzol, gas oil ..
Heavier oils with higher viscosities requires lower velocities - but can be compensated with heating and heat tracing.
Boiler house topics, fuels like oil, gas, coal, wood - chimneys, safety valves, tanks - combustion efficiency.
Pipe lines - fluid flow and pressure loss - water, sewer, steel pipes, pvc pipes, copper tubes and more.
Heat loss from insulated and non insulated sheltered and exposed oil tanks and pipes.
Viscosities and densities of ISO - and equivalent SAE grade oils.
Recommended max. flow velocities on the delivery side when pumping light oils.
Recommended max. suction flow velocities when pumping light oils.
Head or pressure loss due to friction in oil pipes - various viscosity and laminar flow.
Heat loss in W/mK and Btu/hr ft degF from oil tubes ranging temperatures 10 - 38 degC (50 - 100 degF).
Pressure drop in oil pipes - viscosities ranging 100 - 600 Saybolt Universal Seconds.
