For safe production in winter, freezing of the pressure pipes of the instrument is a very troublesome problem. Especially in the cold north of my country, the temperature in winter is low and lasts a long time. The KIP pressure pipeline is often frozen due to the content of the measured environment, resulting in an explosive failure and seriously affecting the safety of production in the winter. The original electric heating system of the instrument sometimes requires an increase in heat dissipation, that is, an increase in thermal energy consumption, that is, the steam consumption is too large, the steam is everywhere in the device, the temperature is low, and the condensed water forms ice cones; when the steam supply is too small, the conductive wire often freezes easily. Which causes the device to fail. For safe production in winter, freezing of the pressure pipes of the instrument is a very troublesome problem.

Heating the instrument pressure pipeline is one of the most difficult tasks for the managers of the instrument. Especially in the cold north. Not suitable if the amount of steam accompanying the steam is too little or too large. It is best to abandon the heating wire or use another medium heater instead.

Electric heating is a heating technology that uses electrical energy as heat, safe and reliable to effectively control the temperature and prevent overheating of the pipeline environment. Due to some problems with steam heating and water heating, electric heating is currently the main method of heating.

A complete electric heating system typically consists of power connectors, electric heating cables, electric heating terminal boxes, three-way junction boxes, double-sided junction boxes, insulation layers, moisture-proof layers and strapping. These devices are mutually complementary and interconnected, if a problem arises in any of the links, this will lead to the failure of the electrical heating system of the PP device.
