Ultra-long distance heating cable The LLHCL is a series of high-efficiency resistance heaters that are used for ultra-long length pipelines requiring temperature maintenance or freezing protection.
Shandong Huaning designed low temperature self-regulating electric heating belt suitable for common areas, hazardous areas, corrosion zones, etc. D. And used to keep heat, prevent coagulation and freezing. The standard color of the low temperature self-regulating electric heating belt is black or blue, and the main belt can withstand temperatures up to 90 °C.
The standard color of Shandong Huaning's ZWK self-regulating mid-temperature electric heating belt is brown, main type, shielding explosion-proof type, protection type, explosion-proof type, explosion-proof and anti-corrosion type, and can withstand temperatures up to 125 °C. After checking the heating efficiency, the power of the electric heating belt should remain at 90% of the original value.
A series of red high temperature self-regulating electric heating cables (self-regulating electric heating cables) developed by Shandong Huaning are widely used for heating, heat preservation, preventing coagulation and freezing of pipelines and storage tanks.
Mineral insulated heating cables are classified according to the outer sheath: mineral insulated heating cable with stainless steel sheath-MISS, mineral insulated heating cable made of stainless steel anti-corrosion outer sheath-(MISS-FEP), mineral insulated heating cable made of alloy 825 sheath-(MISS).

Electric heating cable is a heating method that uses insulation resistance or resistance heating wire to create a temperature after power supply. It can automatically adjust the output temperature and reasonably maintain the process temperature requirements to keep warm, raise the temperature and protect the heating equipment from freezing. The insulation and antifreeze effect of the container is very good.
Transport of heavy oil through the pipeline over long distances and long-term retention in the pipeline will result in a drop in temperature due to heat dissipation and increased viscosity, which will cause the pipeline to be blocked by freezing or condensation-related accidents. Electric heating is widely used as effective insulation of pipelines and anti-freeze protection.
According to the statistics of the Hydrometeorological Center, the average daily minimum temperature at the location of the CNPC tank farm is 5 ° C, and the average daily maximum temperature is 14 ° C. Since the freezing point of the PX is about 15 °C, the supply pipeline needs heat preservation and heating. The oil depot has been in operation for many years without a stable source of steam, therefore, this project is considering the use of electric heating technology.
Long-distance crude oil pipelines with a high paraffin content with freezing temperatures above 50 °C. According to the requirements of the production plan of the plant, the volume of oil transportation through the pipeline is 150 thousand rubles. Tons per year, maximum-200 thousand. Tons per year.. According to the thermodynamic analysis of the pipeline, the initial supply temperature of the pipeline is 80 ° C (TN), and the temperature of the end entering the tank is 60 ° C (Tu). Since the transportation temperature needs to be adjusted according to the time of year, it sometimes needs to be transported by heat.
