The heart of our Leader Heating Electric Radiant Tube is a meticulously engineered heating core, featuring U-shaped resistance wires perfectly aligned axially and securely welded at the ends, supported by robust ceramic frames. This innovative design enables excellent heat dissipation without any interference between the core and its protective sheath. Crafted to withstand temperatures up to 1000 degrees, the resistance wires are made of superior Cr20Ni80 or 0Cr21AI6Nb materials, allowing the surface to efficiently operate at 1200 degrees. Our radiant tubes, constructed from these high-grade materials, are capable of reaching a peak working temperature of 1000 degrees. High alumina ceramics fortify the support frame, while the protective sleeve is a masterpiece of cold drawn, seamless, thin-walled heat-resistant steel pipe, built from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offering exceptional high-temperature oxidation resistance, significant high-temperature creep strength, and notable carburizing resistance. Our design is synonymous with safety, applying a high safety factor throughout. For even greater temperature demands, our electric radiation tube, utilizing 0Cr27AI7Mo2 resistance wire, is rated for a working temperature of 1200 degrees, reaching a dazzling surface temperature of 1400 degrees. Its short-term maximum temperature hits 1250 degrees, with a support frame crafted from resilient steel jade porcelain. The external protective sleeve, a triumph of engineering, is made from a Fe Ni CrAI Re alloy designed for high oxidation resistance. This allows for sustained operation at 1300 degrees Celsius in an oxidizing environment, withstanding short excursions to 1360 degrees Celsius. This radiant tube is ideal for high-temperature, low oxygen partial pressure, and sulfur-containing environments.
