Application of electric tracer cables in thermal insulation of oil and gas pipelines of offshore oil platform
When the temperature is extremely low, it is difficult for the pipeline to guarantee the reliability of the liquid quality, and even problems such as oil solidification and pipeline failure can occur. Therefore, the design of thermal insulation and the construction of oil, gas and water pipelines on offshore oil platforms is an important task.

The construction of thermal insulation pipelines for oil, gas and water on offshore oil platforms is a relatively important environment in the construction of upper blocks Due to the large temperature changes in the marine working environment, the lowest temperature in the Bochai Sea area can drop to-20 °C. When the temperature is extremely low, it is difficult for the pipeline to guarantee the reliability of the liquid quality, and even problems such as oil solidification and pipeline failure can occur. Therefore, the design of thermal insulation and the construction of oil, gas and water pipelines on offshore oil platforms is an important task.
At present, the oil, gas and water pipelines of offshore oil platforms mainly use heat preservation in the heat preservation environment and electric heating. In special cases, these two forms of heat preservation can be used together. The first is mainly based on the low thermal conductivity of the insulating medium (for example, mineral wool, glass wool, rubber and foam, etc. E.) to reduce the loss of heat by the fluid in the pipeline; keep its temperature within the most reasonable temperature range of the process.
Because drilling equipment needs to be in seawater for a long time, the marine environment is complex, easily corrosive, low-temperature freezing of pipelines and other phenomena. Due to the low temperature of the oil pipeline, the paraffin sediments freeze, block the pipeline and affect production, which requires pipeline insulation of the offshore drilling platform equipment. Electric heating is the best choice for heating and insulation of offshore drilling platforms. Our electric heating system has the characteristics of corrosion protection, explosion protection, sterilization and thermal insulation and is applied to the insulation of pipelines of offshore drilling platforms. In addition, in addition to the extraction, storage, transportation, and normal operation and maintenance of some related equipment, including the working state of lubricating oil, oil coolant, etc. D., support for electric heating in extremely low temperatures is required. In such harsh conditions, the normal operation of oil production equipment, normal transportation and storage of oil products are guaranteed.

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.
