Construction stages of mineral insulated heating cable
Mineral insulated heating cables are suitable for freezing protection in industry or construction, as well as for heat preservation and heating of technological environments. How are mineral insulated heating cables arranged?

Mineral insulated heating cable (EadCalle mineral insulated) consists of a metal core (heating body), the core is tightly surrounded by mineral magnesium oxide (insulation layer) and a metal tube (usually copper, steel, etc. E.) which is dragged many times. or stainless steel, alloy 316L, 825 etc. E.). If desired, the layer of anticorrosive outer shell of polyperfluoroethylene and propylene can be extruded outside the metal shell.
Mineral insulated heating cables are suitable for freezing protection in industry or construction, as well as for heat preservation and heating of process environments. Especially for pipelines that require high power output or withstand high temperature steam purging and operate at high temperature for a long time, in environments that require anti-corrosion and explosion safety, the mineral insulated heating cables of the MISS electric heating system can show. Excellent characteristics.
Put the MI heating cable on the pipeline. When the tank and other devices are installed, a heating cable of a certain type and size is laid along the pipeline, bound with stationary wire at an interval of 500mm, laid outside the tank and fixed with wire tips at a set interval. Size.
Armoured MI cables are connected to each other, and the mounting cables are pulled on the terminal. After processing the terminal, the connector must be installed.
When installing the heating cable, generally each control system is equipped with a temperature measurement element, one for temperature control, and the other for determining the temperature difference to sound the alarm.
After laying the heating cable, it is first wrapped with a layer of galvanized iron sheet and then kept warm. The galvanized iron sheet on the heating cable can maintain a constant temperature on the pipe surface to improve heating efficiency.
The material used for heat preservation is the same as other heating methods, because water seepage reduces heat preservation efficiency, so it is very important to carry out waterproof treatment carefully.

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.
