Boiler heating tubes are mainly categorized into stainless steel heating tubes and ceramic heating tubes. The stainless steel electric heating tube is a tubular electric heating element, consisting of a metal tube, spiral-shaped resistance wire, and crystalline magnesium oxide powder. Inside the stainless steel seamless tube, high-temperature resistance wires are evenly distributed, while the gaps are filled with crystalline magnesium oxide powder, which has excellent thermal conductivity and insulation properties. When an electric current passes through the high-temperature resistance wires, the heat generated diffuses through the magnesium oxide powder to the surface of the metal tube. This heat is then transferred to the water inside the boiler, achieving the heating objective. Ceramic electric heating tubes are made from high-quality ceramic substrates and are wound with high-quality electric heating wires, offering high electric heat conversion efficiency, rapid heating, low thermal inertia, high-temperature resistance, corrosion resistance, good thermal-chemical stability, long service life, high insulation strength, and non-pollution. Compared to other electric heating elements, they can save energy by approximately 30%.
