The heating core of the Leader Electric Heater - High-Efficiency Electric Radiant Tube is ingeniously crafted with U-shaped, axially aligned end-welded resistance wires harmoniously supported by ceramic frames. Thanks to the absence of shielding between the core and the protective sleeve, heat dissipation is exemplary. Rated for a working temperature of 1000 degrees Celsius, the resistance wires are made from Cr20Ni80 or 0Cr21AI6Nb, allowing the surface temperature to soar to 1200 degrees. The robust design materials, including high alumina ceramic support frames and an outer protective sleeve crafted from 1Cr25Ni20Si2 or 1Cr25Ni35Si2 steel, ensure outstanding resistance to high-temperature oxidation, carburizing, and high creep strength. The advanced design ensures a high safety factor. For even more demanding applications, a resistance wire of 0Cr27AI7Mo2 enables a rated working temperature of 1200 degrees and a surface working temperature of 1400 degrees. The maximum short-term working temperature is 1250 degrees, with support frames made of steel jade porcelain. The cold-drawn, seamless, thin-walled heat-resistant Fe Ni CrAI Re alloy sleeve provides exceptional oxidation resistance, performing reliably at 1300 degrees Celsius in oxidizing environments, with short-term resistance up to 1360 degrees. Perfect for high-temperature operations in low oxygen and SC containing environments, this product epitomizes cutting-edge engineering and durability.
