Resin storage tank electric heating system
Although there are many ways to heat, steam and water heating have obvious drawbacks, as electric heating has attracted a lot of attention. Generally speaking, the resin storage tank body should be maintained at a temperature of about 40 degrees, so you can choose a self-regulating electric heating cable.

The viscosity of the resin will increase greatly after the temperature decreases in winter. As an example, we take the resin 86-1: at a temperature of 25 ° C, the viscosity is 130 s (4 cups), and when the temperature is reduced to 7 ° C, the viscosity can reach 320 s, increasing by almost 2.5 times. In the northern region or even the eastern region, the lowest temperature in winter is often below 0 °C, the viscosity of the resin will increase, and the material pump will be difficult to transport the resin, and often the material pump will not work, causing the engine to stop. Without solving this difficult task, it will be difficult to carry out paint and varnish production.
Because cheap material pumps are difficult to find, the industry generally heats the resin to keep the resin at a certain temperature to control the viscosity within a certain range so that production can continue normally with heat preservation.

Self-control temperature electric heating cable automatically adjusts the output and compensates according to the actual amount of heat required by the heating system. This is a new generation of constant temperature energy-saving heaters, it can be arbitrarily shortened or lengthened for a certain time. Range and multiple crossovers are allowed. And no need to worry about hot spots of high temperature and fire, easy installation, easy maintenance, all-day maintenance, high automation, low operation and maintenance costs, etc. D.

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.
