The heating core of our groundbreaking electric heating radiant tube is ingeniously designed with U-shaped, axially arranged, end-welded resistance wires, harmoniously supported by sturdy ceramic frames. Distinctly, it features a design without shielding between the inner core and the outer protective sleeve, ensuring exceptional heat dissipation. The electric radiation tube boasts a rated working temperature of an incredible 1000 degrees, utilizing resistance wire materials such as Cr20Ni80 or 0Cr21AI6Nb. Its surface working temperature impressively reaches 1200 degrees. Crafted for the highest performance, it achieves a maximum working temperature of 1000 degrees, with high alumina ceramic parts forming the robust support frame. Externally, a cold drawn seamless thin-walled heat-resistant steel pipe, made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, provides unmatched protection. This specialized material offers remarkable high-temperature oxidation resistance, enhanced creep strength, and resilient carburizing resistance. Our design and material selection elevate safety with a substantial safety factor. Meanwhile, the rated working temperature of the alternative electric radiation tube is 1200 degrees, employing 0Cr27AI7Mo2 for resistance wires. Its surface working temperature soars to 1400 degrees, with a maximum short-term capability of 1250 degrees. The support frame is crafted from steel jade porcelain, while the outer sleeve utilizes a cold drawn seamless heat-resistant steel pipe made from Fe Ni CrAI Re alloy, demonstrating high oxidation resistance. It operates consistently at 1300 degrees Celsius in oxidizing environments and withstands short-term exposure at 1360 degrees Celsius. Ideal for high-temperature, low oxygen partial pressure, and SC-containing environments.
