The various pipelines inside the power plant are like the blood vessels of the power plant, transporting and maintaining the normal operation of the power plant, but in winter, if you want to maintain the normal operation of the power plant, you still need to take certain #electric tracing #heat preservation measures.
Electric heat tracing
For example, power plant instrument pipelines, valves, etc. need to be insulated and traced, the implementation of power plant flue gas desulfurization and denitrification projects, and the use of water pipelines in power plants. Here we mainly introduce the antifreeze insulation scheme of power plant water pipelines.

Because the power plant is a flammable and explosive hazardous occasion, the possibility of explosion protection and mechanical damage protection needs to be considered when selecting pipe insulation electric heat traces. And for the operation and maintenance temperature of the pipeline, only the temperature needs to be maintained at 0-5 °C.
Therefore, it is recommended to choose a low-temperature protection type of electric heat tracing, you can choose two installation methods, flat installation or winding installation, after selecting the installation method, the electric cable is closely attached to the pipeline installation, and with related accessories such as junction boxes, pressure-sensitive tape, etc., you can assemble a complete electric cable system.
Low-temperature protection electric heat tracing products have a metal braid layer, which can play the role of grounding safety protection, and can play a good role in heat transfer and heat dissipation. The use of this type of pipe insulation electric cable can avoid excessive local heating of the pipeline and the appearance of burning marks.
Self-limiting temperature electric heat trace
In addition, protective electric heat trace products have a protective outer sheath of PVC in addition to the metal braid, which can enhance mechanical resistance and moisture resistance. Ideal for hazardous areas of power plants where electrical grounding is required.
