At the heart of efficiency, the heating core of our electric radiant tube is ingeniously crafted from U-shaped axially aligned resistance wires, seamlessly welded at the ends and supported by robust ceramic frames. Unencumbered by shielding between the core and its protective outer sleeve, this design ensures superior heat dissipation. Engineered for excellence, the electric radiation tube boasts a rated working temperature of 1000 degrees with resistance wire options like Cr20Ni80 or 0Cr21AI6Nb. When needed, surface temperatures soar to 1200 degrees, thanks to the high alumina ceramic parts supporting its frame. The outer sleeve, a masterpiece of cold-drawn, seamless, thin-walled heat-resistant steel, crafted from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, showcases exceptional resistance to high-temperature oxidation, creep strength, and carburization. With a high safety factor in design and material selection, this tube delivers reliability and performance. For even more demanding scenarios, the tube achieves a rated working temperature of 1200 degrees, using 0Cr27AI7Mo2 resistance wire. Surface temperatures can peak at 1400 degrees, with short-term working capability at 1250 degrees, supported by steel jade porcelain. The outer sleeve, an innovation of Fe Ni CrAI Re alloy, withstands oxidation in temperatures up to 1300 degrees Celsius, offering short-term resilience at 1360 degrees, perfect for high temperature, low oxygen, and sulfur-containing environments.
