The innovative heating core of the Leader Ceramic Heating Radiant Tube Electric Heater is ingeniously structured with U-shaped, axially aligned, end-welded resistance wires accompanied by sturdy ceramic support frames. This unique design ensures efficient heat dissipation by eliminating any shielding between the inner core and the outer protective sleeve. The electric radiation tube impressively operates at a rated working temperature of 1000 degrees, utilizing high-performance resistance wires made from Cr20Ni80 or 0Cr21AI6Nb, with a remarkable surface working temperature potential of up to 1200 degrees. Crafted for endurance, the maximum operational temperature for this radiant tube design can soar to 1000 degrees, supported by high alumina ceramic parts for exceptional durability. Encasing this core is a cold drawn seamless thin-walled heat-resistant steel pipe, meticulously engineered from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offering supreme high-temperature oxidation resistance, outstanding creep strength at elevated temperatures, and a reliable resistance to carburization. Prioritizing safety and reliability, the radiant tube's design and material choices integrate a high safety factor. An alternative configuration of this radiant tube boasts a rated temperature of 1200 degrees, with resistance wires forged from the advanced 0Cr27AI7Mo2 material, achieving an impressive surface working temperature of 1400 degrees. This configuration is designed to withstand a short-term maximum operational temperature of 1250 degrees, with a support frame crafted from steel jade porcelain. Additionally, the outer sleeve comprises a cold drawn seamless thin-walled heat-resistant steel pipe made of Fe Ni CrAI Re alloy, showcasing extraordinary oxidation resistance. This heater is tailor-made for sustained performance at 1300 degrees Celsius in oxidizing atmospheres, withstanding short-term exposure up to 1360 degrees Celsius. Ideal for demanding environments that involve high temperatures, low oxygen partial pressure, and sulfur-containing conditions, this radiant tube epitomizes cutting-edge technological advancement.
