Abstract RU 2250870 C1

FIELD: pipe transport.

SUBSTANCE: proposed pipeline contains sections, shutoff valves, outer insulating layer and heating element made up of separate sections and connected to electric circuit. Each section of electric heating element is located at inlet of each section and is formed by electric heater in form of coil with turns tightly fitting each other and outer surface of pipeline. Heating element provides temperature 8-15 degrees higher than critical temperature of film boiling of liquid in pipeline to form vapor film on inner surface of pipeline.
