Heat transfer from the heated oil to the surrounding soil significantly affects<br>temperature decrease. Heat losses depend on the full heat transfer coefficient. The flow friction heat slows down temperature decrease in the pipeline and reduces the flow pressure head losses due to friction in the pipeline. The<br>article also analyzes the dependence of the influence of the full heat transfer coefficient with the account of the flow friction heat on the flow pressure head losses in the pipeline when pumping high-viscosity and solidified oils.</p>}, number={1(25)}, journal={Oil and Gas Power Engineering}, author={Якимів, Й.
