Electric heat tracingAs a new type of pipeline insulation product, it has been widely used in industrial, civil and other fields. It has the advantages of simple installation, high heat tracing efficiency and long service life, and is favored by users. However, when selecting and using electric heat tracing, many users often only pay attention to its basic heating performance, and ignore its performance in special environments such as high temperature, high pressure, and high frequency.
The following is a detailed analysis and explanation of the "three highs" performance of electric heat tracing to help users better understand and choose electric heat tracing products.
1.High-temperature performance of electric heat tracing.
High-temperature performance refers to the ability of the electric heat trace to work in a high-temperature environment. Generally speaking, the working temperature range of electric heat tracing is 0 105, but in some special occasions, such as petrochemical, electric power and other industries, electric heat tracing is required to be able to withstand higher temperatures. Therefore, when choosing an electric heat tracing, its high-temperature performance needs to be considered.
In addition, when selecting an electric heat tracing, it is also necessary to consider its high temperature resistance. In general, the high temperature resistance of electric heat tracing is related to its material. Among them, PTC+ metal wire has the best high temperature resistance, followed by nickel-chromium alloy, and PTC is the worst. Therefore, where higher temperatures need to be withstanded, electrical heat tracing made of PTC+ wire or nichrome should be chosen.
2.High-voltage performance of electric heat tracing.
High-voltage performance refers to the ability of the electric heat trace to work in a high-voltage environment. Generally speaking, the working voltage range of electric heat trace is 220V 380V, but in some special occasions, such as electric power, petrochemical and other industries, electric heat trace is required to be able to withstand higher voltage. Therefore, when choosing an electric heat tracing, its high-voltage performance needs to be considered.
In addition, when selecting an electric heat tracing, it is also necessary to consider its high voltage resistance. In general, the high voltage resistance of an electric heat trace is related to its material. Among them, fluoroplastics have the best high pressure resistance, followed by silicone rubber, and glass fiber is the worst. Therefore, where higher voltages need to be withstanded, electrical heat tracings made of fluoroplastic or silicone rubber materials should be chosen.
3.High-frequency performance of electric heat tracing.
High-frequency performance refers to the ability of the electric heat trace to work in a high-frequency environment. Generally speaking, the working frequency range of electric heat trace is 50Hz 60Hz, but in some special occasions, such as high-frequency induction heating, high-frequency welding and other industries, electric heat tracing is required to be able to withstand higher frequencies. Therefore, when choosing an electric heat tracing, its high-frequency performance needs to be considered.
In addition, when selecting an electric heat tracing, it is also necessary to consider its high-frequency resistance. In general, the high-frequency resistance of electric heat tracing is related to its material. In applications where higher frequencies need to be withstanded, electrical heat tracing made of copper-nickel alloy or nickel-chromium alloy material should be selected.
In short, the influence of factors such as high temperature, high pressure and high frequency needs to be paid attention to during the use of electric heat tracing. Reasonable control of these factors can effectively extend the service life of electric heat tracing, improve its work efficiency and reliability.
