What is electric heating cable? As a high-tech product in the new era, electric heating cables are rarely understood. Many people may think that hearing this name is a technology that is far away from the lives of ordinary people. In fact, it is not the case. Although it does not have a strong sense of existence, it exists in every corner of our lives.
Electric heating cables are widely used in pipelines that are easy to liquefy, solidify, crystallize and viscous fluids, valves, pumps, containers, tanks, tanks, reactors, etc. During the production process of paper, it can generate heat through electric current, transfer the heat to the paper, and make the paper dry quickly.
Some people ask that the self-limiting heating cable is a parallel heating cable, the voltage of the first and last sections should be equal, and the heating temperature of each section should be equal. How can there be a low heating temperature at the end? This should be analyzed from the principle of voltage difference and the principle of self-limiting temperature.
Nowadays, the logistics industry is developing rapidly, and each region has its own logistics distribution center. While some logistics bases undertake the logistics distribution function, they also need to take into account the impact of weather factors on logistics warehouses, especially in northern winter, where snow accumulates on the roof. The snow on the roof is a pressure on the roof. If the roof structure is not strong, it will collapse. At the same time, the snow will melt on a large scale in warm weather, causing the road surface to be wet, which is not conducive to the transportation of goods. In short, all kinds of inconveniences require gutter snow melting power The heat tracing belt melts snow and ice.
Electric heating cables are used for the insulation of bio-oil pipelines to ensure that the bio-oil remains within a suitable flow temperature range. By installing electric heating cables on the outside of the bio-oil pipeline, continuous heating can be provided to maintain the temperature inside the pipeline. Bio-oil is a renewable energy source usually derived from vegetable or animal oils. During the transportation process, the temperature of bio-oil needs to be kept within a certain range to ensure its fluidity and quality.
There are four main types of heating cables, which are self-limiting temperature heating cables, constant power heating cables, MI heating cables and heating cables. Among them, the self-limiting temperature electric heating cable has more advantages than other electric heating cable products in terms of installation. First of all, it does not need to distinguish between live and neutral wires during installation and connection, and is directly connected to the power supply point, and does not need to be used in conjunction with a thermostat. Let us briefly describe the installation of the self-limiting temperature heating cable.
As a kind of anti-freezing and heat preservation method, electric heat tracing system is chosen by more and more users. Due to climate reasons, some equipment may freeze and damage when operating at low temperatures. Especially for measuring instruments, if insulation measures are not taken, it will affect their accuracy and cause errors. The electric tracing belt can be used for freezing insulation of measuring instruments.
The fire water tank is one of the important safety facilities in the building, which is mainly used to store fire water and ensure that the water supply can be timely when the fire occurs. In the cold winter, in order to prevent the water in the tank from freezing, affecting the normal use of fire water, insulation measures need to be taken. Southern warm areas in winter fire water tank only need to cover a layer of insulation, however, in the cold northern regions, due to the low temperature, it is necessary to take more measures for water tank insulation, to ensure that the liquid in the water tank is not frozen, of which electric heat tracing insulation is a common way of insulation, can effectively maintain the temperature of the water in the fire tank. So, which kind of electric tracing heat insulation should be used in the fire water tank?
In the petrochemical industry, insulation is a crucial link. Petrochemical tank is a common equipment used to store various chemical substances, in order to ensure the stability and safety of the substances in the tank, the tank insulation is essential. Among them, the hot belt is a commonly used thermal insulation product, which plays an important role in the thermal insulation of petrochemical tanks.
