●The single-head heating tube has sufficient heat resistance, that is, it does not oxidize or oxidize at high temperature;
● has a certain mechanical strength at high temperatures;
●The single-head heating tube has a larger specific resistance, otherwise the electric heating tube has to be made very long, which is not convenient to install;
● The smaller the temperature coefficient of resistance, the better;
●Good processing performance, can be processed into linear, ribbon or spiral, and has good welding performance;
● Long-term work does not age;
●The source of single-head heating pipe is based on domestic and low cost. Of course, the electric heating tube with high requirements is completely imported electric heating wire.
