Oil pipes flow velocities should be kept within certain limits.
The table below can be used when designing oil pipes:
Oil Pipes - Recommended Flow Velocities
|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.
