FIELD: oil producing industry; oil refining industry; petrochemical and chemical industries; transportation of high-viscosity Newtonian and non-Newtonian liquids via pipe lines.
SUBSTANCE: proposed method includes forming coaxial concentric layer of water at inner surface of pipe by adding water to oil and setting the oil and water flows in rotary motion effected by bladed mixers mounted after sections where velocities of flows change by magnitude or direction at angular velocity determined by the following formula: 
where ω is angular velocity of bladed mixer rotation; g is free fall acceleration and R is radius of pipe line.
EFFECT: reduction of hydraulic resistance and power requirements due to forming rotary motion of flows behind sections where their velocities change in magnitude or direction.
