FIELD: technological processes.
SUBSTANCE: in method of high-viscous liquids traveling in pipeline with wall layer from the fluid solution, at that in the capacity of liquid viscoplastic fluid is used and ratio of radius of wall layer of viscoplastic fluid solution and radius of pipeline is 
where r, R - accordingly radius of viscoplastic liquid wall layer and radius of pipeline, m; τ0 - limit shear stress of viscoplastic liquid solution, Pa; η - plastic viscosity of viscoplastic liquid solution, Pa s; μ - viscosity of pumped liquid, Pa s; Δp - pressure difference in pipeline, Pa; l - pipeline length, m.
EFFECT: reduction of hydraulic resistance and power inputs for hydraulic transport of highly viscous liquids.
