Huaning is the development and development of new product, manufacture, sale, engineering construction, maintenance and repair of high viscosity oil, high condensation oil well hoisting (physical oil extraction method), heating of pipelines (liquid or gas), heating of pipelines. Service-oriented enterprise, its technologies and products are widely used in high-viscosity oil, high-temperature oil, heavy oil, water injection wells, screw pump wells, SAGD wells and other electric heating, as well as oil wells, gas wells, water well testing and other fields, Are also used for heating or heating pipelines of petrochemical enterprises, unlocking or thawing pipelines, heating boilers and other systems. It is an important partner of large and medium-sized oil fields such as Liaohe Oil Field, Shengli Oil Field, Daqing Oil Field, Horqin Oil Field, Xinjiang Oil Field, Changqing Oil Field, Zhongyuan Oil Field, etc. D. It is widely used for heating and heating pipelines, unblocking pipelines and thawing.
The continuous steel pipe heating system is an electric heating system that integrates heating and thawing in oil and gas production, liquid and gas transportation through pipelines. Since the cable protective layer is a steel pipe, it is compatible with P46, polyethylene, polypropylene cables. And other materials. In comparison, it has the characteristics of high mechanical strength, high extrusion resistance, oil resistance, pressure resistance, corrosion resistance, high temperature resistance, long service life, renewable, etc. D., so it is widely used in the petroleum industry.: "oil exploration, oil extraction, refining, refining, storage, collection and transportation" and other production processes.
The principle of the continuous steel pipe heating system is to compensate for the heat loss of the liquid in the pipeline, to ensure the thermal balance of the fluid in the pipeline, and to ensure a certain fluid flow in the pipeline.
The composition of the continuous steel pipe heating system: The continuous steel pipe heating system consists of two parts: the intelligent power control of the continuous steel pipe heating cable and the continuous steel pipe heating cable.
The steel pipe continuous heating system developed by Huaning company strictly meets the relevant IEC and IEEE electric heating standards and uses the reliability design mentioned in the project technical requirements to ensure the absolute safety of the facility. Huaning is engaged in the continuous heating system of steel pipes and is ready to provide professional heating products and services for customers who need and want to use the continuous heating system of steel pipes.
In recent years, the hollow rod electric heating system has been widely used in heavy oil units in various oil fields due to simple equipment design, convenient on-site construction, easy maintenance and management, and is a good product to solve the crude oil problem. Oil lifting. The electric heating system with hollow rods is a complex of dimensional equipment, consisting of hollow rods, heating cables, power sources, etc. It uses the thermal energy generated by electric heating to heat the crude oil in the oil pipe throughout the process to reduce the viscosity of the crude oil, prevent the deposition of paraffin in the oil pipe, improve the fluidity of the crude oil and achieve the goal. Increase in productivity and efficiency.

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.
