Among the many methods of ice control, it can be said that the method of ice control by electric heating has little effect on the operation of the lock and does not compromise the safety of the lock and hydraulic structures. The technical solution is also very simple to implement, and it can also be operated under dry water channel conditions. Which can meet the needs of preventing and controlling the danger of freezing and icing.

Malfunction and methods of treatment of electric heating on the offshore oil well platform
The third type of fault and its treatment method The phenomenon of fault is that the electric heater belt is not hot or the heating and cooling are uneven. This can be: lack of insulation; the insulation layer is too thin or uneven in thickness; power work, serious loss of energy costs. Treatment method: choose the electric heating belt from the ordinary manufacturer that was in operation, with the correct certificates and marked nameplate, various technical indicators and dates of manufacture, make insulation, install it according to the product instruction, and make the waterproofing layer according to authority. Temperature message layer to make the electric heating belt work in a dry state.

Technical requirements for the installation of electric heating on offshore oil platforms
Oil and gas pipelines are the main part of the offshore platform construction project. In the long-term operation of the pipeline, in conditions of severe external weather conditions, the operational condition of the pipeline will be disrupted to varying degrees, so the oil and gas pipelines must be isolated. Oil and gas pipelines are the main part of the project for the construction of the offshore platform. With long-term operation of the pipeline in conditions of severe external weather conditions, this will affect the working condition of the pipeline to varying degrees, so the gas oil pipeline must be isolated.

What electric heating cables can generally be used on offshore oil platforms
The offshore platform performs tasks of oil production, oil storage and transportation of oil products through pipelines to tankers for transportation to land. The use of electric heating allows the oil production equipment of the offshore oil platform to work normally, and oil products to be transported and stored normally in such harsh conditions.

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.

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.
