Introducing the sophisticated heating core of the Leader Electric Heater's radiant tube: a marvel of engineering composed of U-shaped, axially arranged end-welded resistance wires paired with ceramic support frames. Remarkably efficient, this design features an unshielded core, promoting excellent heat dissipation. Operating at a rated temperature of 1000 degrees, the resistance wire is crafted from high-quality Cr20Ni80 or 0Cr21AI6Nb, with surface temperatures soaring to 1200 degrees. The pinnacle of temperature capability for this radiant tube hits 1000 degrees, with the core support frame elegantly formed from high alumina ceramic parts. Encasing this innovation is a cold drawn seamless thin-walled heat-resistant steel pipe, made from the robust 1Cr25Ni20Si2 or 1Cr25Ni35Si2, known for its superior high-temperature oxidation resistance and impressive creep strength at elevated temperatures, as well as notable resistance to carburizing. This expertly designed radiation tube boasts a high safety factor, confidently operating at a rated working temperature of 1200 degrees with resistance wire material 0Cr27AI7Mo2, reaching surface temperatures of 1400 degrees. Its maximum short-term working temperature ascends to 1250 degrees, supported by steel jade porcelain frames. The outer protective layer is constructed of a cold drawn seamless thin-walled heat-resistant steel pipe made from Fe Ni CrAI Re alloy, exhibiting exceptional oxidation resistance, capable of enduring up to 1300 degrees Celsius in oxidizing atmospheres and short-term resistance to 1360 degrees Celsius. This radiant tube is ideally suited for high-temperature applications in low-oxygen partial pressure and SC-containing environments.
