Boiler heating tubes are primarily categorized into stainless steel heating tubes and ceramic heating tubes. The stainless steel electric heating tube is a tubular electric heating element, composed of a metal tube, helical resistance wire, and crystalline magnesium oxide powder. Inside the stainless steel seamless tube, high-temperature resistance wires are evenly distributed, with gaps filled with crystalline magnesium oxide powder that excels in thermal conductivity and insulation. When current flows through the high-temperature resistance wires, the heat generated is diffused 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 with a high-quality ceramic matrix and are wound with high-quality electric heating wires, boasting high electric heat conversion efficiency, rapid temperature rise, low thermal inertia, high resistance to high temperatures and corrosion, excellent thermal-chemical stability, long service life, high insulation strength, and are pollution-free. Compared to other electric heating elements, they can save energy by about 30%.
