今日出廠產品展示及部分報價

本實用新型涉及一種電加熱管,尤其是一種家用電熱水器的電加熱管。該電加熱管由電加熱元件、導熱絕緣材料及金屬套管組成,所述金屬套管的外壁附有表面粗糙度小于0.8μm、含金量大于等于18K的金合金鍍層。由于金合金鍍層與金屬套管基體結合牢固,表面極為光滑,導熱性能好,化學性質穩定、耐腐蝕、耐高溫,因此本實用新型的電加熱管具有性能可靠、不易聚集水垢、使用壽命長的優點。
The utility model relates to an electric heating pipe, especially an electric heating tube electric heater. The electric heating pipe comprises an electric heating element, heat insulating material and a metal sleeve pipe, the outer wall of the metal casing with gold alloy coating surface roughness less than 0.8 μ m, the gold content is greater than or equal to 18K. Because of the firm combination of gold alloy coatings and metal casing body, the surface is very smooth, good thermal conductivity, chemical stability, corrosion resistance, high temperature resistance, so the utility model of the electric heating tube has the advantages of reliable performance, not easy to long life advantages of scale, the use of aggregation
