Selection of type of electric heating cables for chemical pipelines
In the process of storage and transfer of chemical media, heat loss is inevitable. Many environments with high melting point, high viscosity, easy to hacken and easy to moisture, which will affect the material properties if the temperature cannot reach the required process temperature seriously affect normal production. The electric heating cable uses electric heating to compensate for the heat loss dissipated by the heating pipeline and equipment in the process to ensure that the temperature of the medium meets the specific requirements of the process.

In the process of storage and transfer of chemical media, heat loss is inevitable. Many environments with high melting point, high viscosity, easy to solidify and easy to moisture, which will affect the material properties if the temperature cannot reach the required process temperature seriously affect normal production. The electric heating cable uses electric heating to compensate for the heat loss dissipated by the heating pipeline and equipment in the process to ensure that the temperature of the medium meets the specific requirements of the process.
Whether the electric heating product and the design chosen or not are correct depends not only on whether the entire electric heating system can work normally, but also on investment costs, operating costs, operational quality and product life. The requirements for the thermal insulation of the process environment and the amount of heat compensation of the system are the main factors determining the choice of the electric heating system. If there is no research on the calculation and optimization of electric heating products, this not only affects the smooth progress of the process of debugging on and temperature rise, but also creates unnecessary problems during subsequent operation and maintenance.
According to the input conditions, such as the power supply conditions and the length of the pipe to collect the load on the network, the model of the product with the electric heating cable is determined. Taking into account the environment and technical requirements for the electric heating system, as well as the operational performance of the product, the choice is based on the principles of economy, applicability and optimal distribution.
Electric heating cables are divided into self-regulating type, constant power type, mineral insulated heating cables of mi type, etc. D. Self-regulating heating cables have a low range of heat resistance and are suitable for temperature control. The heating cable gives the best results and is suitable for laying in places with a large number of valve taps where cross-overlapping can occur.
Constant power electric heating cable has a range of high temperature resistance, which is suitable for pipelines with strict temperature control. The constant power electric heating cable is divided into parallel type and series type. Very high power electric heating cables are generally limited to the length of the section. If the section length cannot be found when cutting, this part of the electric heating cable will not work. This will not only affect the heating effect of the pipeline, but also cause waste, so cutting is not allowed.
Serial electric heating cables and mineral insulated heating cables are more suitable for long or conventional piping. It is necessary to determine the exact length required according to the actual length of the project. The estimated power and required length should be precisely aligned with the actual length of the local pipeline before use, check. The MI type heating cable has a range of resistance to high temperatures and is suitable for operating conditions in which the pipeline maintains a high temperature or sometimes high maximum operating temperature.
Of course, many factors must be considered when choosing a suitable electric heating cable for chemical pipelines. For example, determine the thickness of the insulation layer. Calculation of compensation for heat loss and additional heating. Mounting length and method of laying electric heating cable etc. These professional problems can be transferred to the electric heating cable manufacturer to help you solve them later.

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.
