The core of the Versatile Leader Ceramic Heating Radiant Tube Electric Heater, a marvel of engineering, is crafted with precision and expertise. It features U-shaped, axially aligned resistance wires supported by robust ceramic frames, ensuring unmatched heat dissipation due to the unobstructed design between the core and the protective sleeve. Designed to achieve a rated working temperature of 1000 degrees, the resistance wires are meticulously made from either Cr20Ni80 or 0Cr21AI6Nb, facilitating a surface working temperature reaching up to 1200 degrees. Constructed from high alumina ceramic, the support frame enhances durability, while the outer sleeve, made from cold-drawn seamless thin-walled heat-resistant steel (1Cr25Ni20Si2 or 1Cr25Ni35Si2), boasts superior high-temperature oxidation resistance, remarkable creep strength, and carburizing resistance. Each material choice in this radiant tube underscores a commitment to safety and performance. For applications demanding even higher temperatures, the advanced resistance wire material 0Cr27AI7Mo2 supports a rated working temperature of 1200 degrees, achieving surface temperatures of 1400 degrees. The electric radiation tube, capable of reaching up to 1250 degrees briefly, is encased in a cold drawn seamless thin-walled heat-resistant steel pipe constructed from Fe Ni CrAI Re alloy, renowned for its high oxidation resistance. This ensures long-term reliability even at 1300 degrees Celsius in an oxidizing atmosphere, withstanding up to 1360 degrees Celsius for short durations. This exceptional product is ideal for extreme environments characterized by high temperatures, low oxygen partial pressures, and the presence of sulfur compounds.
