Fluidity curves of Doluna's oil were constructed, mathematical models for dependency of landslip static tension, landslip limit-dynamical tension and plastic viscosity from the temperature were developed. Generalized analytical representations for dependency of landslip limit-dynamical tension and plastic viscosity from preheating temperature and pipeline residence temperature were proposed.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
