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.
