PIPELINE HEATER Russian patent published in 2014 - IPC F16L53/00 F28D21/00 F17D1/18 

FIELD: heating.

SUBSTANCE: heater comprises heating units, each of which is located around the heated pipeline and comprises the heat insulating layer with the electrical heating element built in it, connected to current-carrying wires. The heating unit located at the beginning part of the pipeline is formed as a heat exchanger with the intermediate coolant using the thermal energy of the condenser of superheated steam of the nuclear reactor. Each subsequent heating unit is provided with a temperature sensor of the pipeline wall electrically connected to the control processor located in a control unit of the maritime platform. The heating element of each heating unit comprises a mechanism of start and stop of contact with current-carrying wires interconnected with the control processor. The pipeline with the heating sections and current-conductive elements are placed in a single heat insulated casing.

EFFECT: stable maintenance of the specified temperature range of the product pumped through the main pipeline under conditions of the cooling effect of the environment.
