Application of electric tracer cable in antifreeze oil tank drying pipeline
In the food oil depots of sales companies, as a rule, it is difficult to carry out winter antifreeze work due to the lack of steam, which has always worried the workers of warehouses and transport workers of oil products. In particular, the first priority was to qualitatively antifreeze the drain pipe of the finished oil tank, safely survive the winter and prevent oil leakage emergencies.

In the north of my country after winter, the ambient temperature can reach-30 ° C and even lower. In such low temperatures, a large number of outdoor equipment, pipelines, valves, etc. D. It is necessary to heat and isolate to effectively prevent the equipment from freezing and ensure that there are no emergencies.
In the product oil depots of sales companies, as a rule, it is difficult to carry out winter antifreeze work due to the lack of steam, which has always worried the workers of warehouses and transport workers of petroleum products. In particular, the first priority was to qualitatively antifreeze the drain pipe of the finished oil tank, safely survive the winter and prevent oil leakage emergencies.
At the chemical plant in Hulunbeyer, Inner Mongolia, a 500-meter residual oil pipeline and a drying pipeline at the bottom of the liquefied petroleum gas storage tank were used to prevent freezing with electric heating, and obvious results were obtained.
The electric heating uses electrical energy to generate heat and evenly distributes heat over a long pipe or large plane Compared to other heating methods, it has the following advantages:
The electric heating device is simple, with uniform heating, accurate temperature, and fast response. which makes it possible to realize automatic control and reduce the labor intensity of workers.
High reliability, explosion safety, fire safety and all-weather. Long service life, no leakage in the transmission and no environmental pollution. Suitable for freezing protection and heat preservation of various pipelines and appliances. A 220 V power source is used to supply electricity. The protection level of its electric heating belt, explosion-proof thermostat, explosion-proof junction box and other accessories is IP54, which allows it to be used in explosive gases in Zone 1 and Zone 2. and fully meets the requirements of explosion-proof around the dehydration pipeline in the area of the oil tank.
Energy conservation. The electric heating product is flat, and the aluminum foil tape can form a wide heat exchange surface that is attached to the pipe surface and the valve body, and the heat exchange rate reaches 90%-96%. The energy loss is small, the heating speed is high, the thermal efficiency is high, and the heating temperature can be adjusted arbitrarily according to the change in ambient temperature.
Protect the environment and reduce pollution. Electric heating will not cause the phenomenon of "running, leaking, dripping" pollution.
Reducing design, construction and maintenance costs. The scope of the design work is small, the structure is simple, the cycle is short, the maintenance is convenient, and the daily maintenance workload is low.
With the development of modern industry, the electric heating method is widely used for anti-freezing, anti-condensation and heat preservation of pipelines, valves, containers and tools in petroleum, chemical, energy, video, offshore platforms and other places, and quickly replaced steam, Heat Water and other freezing protection methods have become a sharp tool for heating and heat preservation.

Electrical heating installation precautions
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.
Which electric heating should be chosen for the main pipeline transport of heavy oil
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.
Which electric heating cable should be considered for a 4 km pipeline
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.
Application of outdoor electric heating cable in oil main pipelines with high paraffin content
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.
What heating product to choose for main infusion pipelines
In petrochemical engineering, trunk infusion pipelines are the lifeblood of the factories. The temperature in the northern region is too low in winter and the pipeline needs to be insulated to compensate for the heat loss due to the low temperature in winter to ensure the normal operation of the pipeline.
The role of leather tracer cables in the insulation of asphalt main pipelines
The toughness of the asphalt is greatly affected by the temperature. When the temperature decreases, the toughness of the asphalt increases, and the drop in resistance of the asphalt during pipeline transportation increases; when the temperature falls below the freezing point, the asphalt solidifies, causing the pipeline to clog and the conveyor belt to come to trouble. Therefore, electric heating and heat preservation during the transportation of asphalt are very important.
