Electric heating tube, the core component of electric heater, must have high thermal efficiency, long-term high temperature resistance, corrosion resistance and good insulation performance and electrical strength under long-term working conditions, so as to ensure its long-term stability, reliability and safety. For this reason, on the one hand, we choose the best quality materials, on the other hand, we use foreign advanced manufacturing technology (our company is the only one in China that can use foreign advanced technology), which makes the technical performance characteristics of our electric heating tubes very significant. Selection of heating wire: the most famous high temperature alloy resistance wire (ni80cr20) of Kanthal company in Sweden is selected as the heating wire material, and the filling material of heating tube selected by the company is the product of mexos mineral products company in the United States, with the model of 22sr.
