Shandong Huaning Electric Heating Technology Co., Ltd.
The constant power electric heating belt is used for electric heating of the wastewater tank.
The electric heating cable uses the heat generated by the heating belt itself to compensate and maintain the heat lost by the oil storage tank to keep the flow to the most acceptable process temperature. The electric heating is evenly laid on the surface of the tank. It differs from the high-concentration heating device in a small area. The electric heating has a low temperature gradient and strong thermal stability. The power is significantly lower than that of the electric heating. Other electric heating devices. Suitable for long-term use.

Suitable for long-term use.
The heating method of the electric belt is to maintain the oil temperature in the pipe by uniformly placing the heating belt on the surface of the tank. Compared with the electric heating method of crude oil: 1. The oil is heated evenly to ensure the continuous fluidity of the crude oil; can be put into operation immediately without the stage of preheating the crude oil in the tank, 3. No need for direct contact with the oil product, convenient maintenance and overhaul, accurate temperature control, long service life, low power consumption and low price.
Commonly used electric heating cables are constant power electric heating cables, self-limiting temperature electric heating cables, etc. D. In 2016, we delivered constant power electric heating cables for the waste oil tank at the oil and gas station in Changchun, CNOOC.
The power bus of the constant power electric heating cable is two parallel insulated copper wires, the heating wire is wound on the insulation layer, and the heating wire is connected to the bus at a certain distance to form a parallel resistance. The constant power electric heating cable has a constant calorific value per unit length. The starting current is small, and there is practically no power attenuation during operation. The constant power electric heating cable must be used with the thermostat so that different temperatures can be selected in different seasons, so as not to affect the oil temperature in the tank.
In view of the electromagnetic induction principle, the electric heating belt winding method should not be wound in a circle as much as possible The purpose is to reduce the magnetic field strength and avoid the differentiation and location of the internal charge of the crude oil in the tank. It is therefore wound vertically sinusoidal. Temperature sensor, explosion-proof terminal box, etc. d.
Thus, electric heating has the advantages of high thermal efficiency, energy saving, simple construction, convenient construction and maintenance, and long service life. And widely used in oil, gas, chemical industry, electric power, construction, food industry and other fields.

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.
