Multiple Diameter Options

The diameter of the pipeline is a crucial parameter that determines the volume of oil that can be transported, the pressure required to pump the oil, and the overall cost of the pipeline. For long-distance oil transportation, larger diameters are generally preferred to allow greater volumes of oil to be moved. 

However, the selection of pipe diameter is influenced by several factors, including the type of crude oil, the expected flow rate, the distance of transportation, and the topography of the region.


20 inches (508 mm)

This diameter might be used for moderate volume transportation. It's a relatively standard size for oil pipelines and could be a cost-effective choice if the required volume isn't exceedingly high.

30 inches (762 mm)

This diameter could be used for a high volume, long-distance oil pipeline. It's a popular choice for some of the world's most significant oil pipelines.

36 inches (914 mm)

Used for high volume transportation, a 36-inch diameter pipeline can move substantial quantities of oil, but it will also require more material to construct, potentially increasing costs.


42 inches (1067 mm)

This is one of the largest diameters commonly used for oil pipelines and allows for the highest volume transportation. However, a 42-inch pipeline will be the most costly to build and maintain, and it may present more significant engineering challenges.
