Oil Pipes - Recommended Flow Velocities
Oil pipes flow velocities should be kept within certain limits.
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.
• Fluid Flow and Pressure Loss
Pipe lines - fluid flow and pressure loss - water, sewer, steel pipes, pvc pipes, copper tubes and more.
Oil Pipes - Head Loss
Head or pressure loss due to friction in oil pipes - various viscosity and laminar flow.
Oil Pipes - Heat Loss
Heat loss in W/mK and Btu/hr ft oF from oil tubes ranging temperatures 10 - 38oC (50 - 100oF).
