Selection of electric heating type of oil and gas storage and transportation facilities
Currently, the systems for collecting and transporting oil and gas from petrochemical enterprises in my country, as a rule, use steam and hot water heating technology and heat preservation transportation technology, but for various long pipelines and pipelines whose environmental temperature is maintained above 150 ° C. To solve such problems, electric heating, a new energy-saving technology for storing and transporting oil and gas, is widely used abroad and is actively promoted in China.

At present, the oil, gas and gas transportation systems of petrochemical enterprises in my country mainly use steam and hot water heating and heat preservation technology, but for various pipelines, pipelines with a temperature above 150 °C and heat-sensitive pipelines, which should be strictly controlled by temperature, For pipes with narrow gaps, complex shapes and heating of non-metallic pipes, the above methods are often powerless. To solve such problems, electric heating, a new energy-saving technology for storing and transporting oil and gas, is widely used abroad and is actively promoted in China. Electric heating converts electrical energy into thermal energy through the electric belt and gives off heat evenly along the length of the surface of the heated object or over a large area. The electric heating cable mainly plays the role of heating, so it is also called electric heating cable, heating cable, heating cable, etc. D.
Electric heating products can be widely used for heat preservation, protection against freezing and condensate of pipelines, pump housings, valves, tanks and tanks in petroleum, chemical, shipbuilding, pharmaceutical, food, engineering and other industries. At present, the oil system is mainly used for antifreeze and anti-condensation of oilfield installations for pumping water and Christmas trees; heating and conservation of pipelines at oil pumping stations and drying stations; antifreeze of water pipelines on drilling platforms and oil production platforms. As well as electric heating and insulation of oil pipelines. Petrochemical enterprises are mainly used for antifreeze, anti-condensation, heating and heat preservation of lubricating oil, residual oil, asphalt, catalyst, gas and other pipelines and media tanks; wait.
Explosive gas mixtures are usually formed around medium pipelines, tanks and tanks in petroleum, chemical and other industries that are classified as explosive areas. All kinds of electric heating tapes can only be used in appropriate explosion-proof rooms if they form a complete machine or system with corresponding explosion-proof electrical products or components and have an explosion-proof certificate for the whole machine or system. Explosion-proof electrical accessories for various electric heating cables mainly include: explosion-proof power junction box, explosion-proof double-sided junction box, explosion-proof three-way junction box, explosion-proof shank junction box, explosion-proof temperature controller and explosion-proof junction box, etc. D. Electric heating cables should be used together with special explosion-proof electrical accessories to ensure safe operation.
Most oil and gas storage and transportation locations are explosive locations, so the design of explosion-proof electric heating must be consistent with the current national (or industry) SYJ25-87 "Oil and Gas Explosive Area Zones": Design Rules, etc. Hazardous places formed by explosive gas mixtures formed during the collection, processing and storage of oil and gas at oil and gas production facilities and devices must be divided according to the relevant standards so that electric heating products and explosion-proof electrical appliances can be reasonably selected.

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.
