Detailed explanation of components of electric tracing belt

　　Electric tracing belt is a kind of pipeline insulation and anti-freezing equipment widely used in petroleum, chemical industry, electric power, construction and other fields. It generates heat through electrothermal effect, provides continuous heat tracing effect for the pipeline, ensures the normal flow of fluid and prevents the pipeline from freezing due to low temperature. The characteristics of high efficiency, energy saving, safety and reliability of electric heat tracing make it widely used in many industries.

　　This paper will introduce in detail the main components and functions of the electric tracing belt.

　　I. Conductive Core Wire

　　Conductive core wire is one of the core components of electric heat tracing belt, which is responsible for transmitting electric energy to other parts of heat tracing belt. Conductive core wire is usually made of copper or other metals with good electrical conductivity, which has good electrical conductivity and mechanical strength. The quality of conductive core wire directly affects the heating effect and service life of electric tracing tape. Therefore, when selecting conductive core wire, materials with good quality and conductivity should be selected.

　　Second, the insulation layer

　　The insulating layer is located outside the conductive core wire, which plays a role in isolating current and protecting it, ensuring that the current only flows in a specific path, and preventing leakage and electric shock accidents. The insulating layer is usually made of high temperature resistant and corrosion resistant materials, such as polytetrafluoroethylene (PTFE) and polyvinyl chloride (PVC). The quality of insulating layer directly affects the safety and reliability of electric tracing tape. Therefore, when selecting insulation layer, materials with excellent quality and good insulation performance should be selected.

　　Third, the heating layer

　　The heating layer is one of the key components of electric heat tracing belt, which is made of conductive material. When current passes through it, it will generate resistance heat to provide heat tracing for the pipeline. The material selection of the heating layer directly affects the heat tracing effect and the service life of the product. Commonly used heating layer materials are nickel-chromium alloy, iron-chromium-aluminum alloy and so on. These materials have good electrical conductivity and high temperature resistance, and can work stably for a long time.

　　Fourth, the outer sheath

　　The outer sheath is the protective layer of the electric tracing belt, which has the characteristics of wear resistance and corrosion resistance, can resist the physical and chemical effects of the external environment and ensure the stability and durability of the electric tracing belt. The outer sheath is usually made of high temperature and corrosion resistant materials, such as stainless steel and polyurethane. The quality of the outer sheath directly affects the service life and safety of the electric tracing belt. Therefore, when selecting the outer sheath, materials with excellent quality and good protective performance should be selected.

　　V. Temperature controller

　　Temperature controller is an important part of electric tracing system, which is used to control the heating temperature of electric tracing belt. The temperature controller automatically adjusts the power output of the electric tracing belt by detecting the temperature change in the pipeline, so as to realize accurate temperature control. Temperature controller is usually composed of temperature sensor, controller and actuator. The quality of the thermostat directly affects the stability and reliability of the electric tracing system. Therefore, when choosing a thermostat, products with good quality and high control accuracy should be selected.

　　Sixth, the junction box

　　The junction box is an important part of the electric tracing system, which is used to connect the electric tracing with the power supply. The junction box is usually made of insulating material, which is waterproof, dustproof and corrosion-proof. Terminal blocks are arranged inside the junction box for connecting the electric tracing belt and the power supply. The quality of junction box directly affects the safety and reliability of electric tracing system. Therefore, when selecting junction boxes, products with good quality and protective performance should be selected.

　　Seven, two-way, three-way, end and other accessories

　　Accessories such as two-way, three-way and tail end are important parts of the electric tracing system, which are used to connect different parts of the electric tracing belt and realize the flexible arrangement and installation of the electric tracing belt. These accessories are usually made of insulating materials, which are waterproof, dustproof and corrosion-proof. The quality of these accessories directly affects the safety and reliability of the electric tracing system. Therefore, when selecting these accessories, products with good quality and protective performance should be selected.

　　Through a detailed discussion of the components of the electric tracing belt, we can draw the following conclusions:

　　1. The components of electric tracing tape include conductive core wire, insulating layer, heating layer, outer sheath, temperature controller, junction box, two-way, three-way and tail end. These components undertake different functions, and together constitute a complete electric tracing system.

　　2. The quality of each component of the electric tracing belt directly affects the stability and reliability of the electric tracing belt system. Therefore, when selecting various components of electric tracing belt, products with good quality and stable performance should be selected.

　　3. The selection and collocation of each component of the electric tracing belt should be comprehensively considered according to the specific application scenarios and requirements. Only by reasonably selecting and matching the components of the electric tracing belt can we give full play to the characteristics of high efficiency, energy saving, safety and reliability of the electric tracing belt, and provide users with high-quality pipeline insulation and antifreeze solutions.

　　To sum up, as an efficient, energy-saving, safe and reliable pipeline insulation and anti-freezing equipment, electric tracing belt has important application value and broad market prospects.
