Discover the cutting-edge technology of our electric heating radiant tube, meticulously crafted for optimal performance and seamless integration into your heating systems. The core is a marvel of engineering, with U-shaped, axially arranged resistance wires welded at the ends, supported by ceramic frames to ensure efficient heat dissipation. This design eliminates any shielding between the core and outer protective sleeve, enhancing thermal efficiency. The electric radiation tube operates at a rated temperature of 1000 degrees, using top-tier materials like Cr20Ni80 or 0Cr21AI6Nb for the resistance wire, capable of surface temperatures reaching up to 1200 degrees. Crafted from high alumina ceramic, the support frame ensures durability, while the cold drawn seamless thin-walled heat-resistant steel pipe, made of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, provides excellent high-temperature oxidation resistance, creep strength, and resistance to carburizing. For more demanding applications, our advanced design allows for a rated working temperature of 1200 degrees and surface temperatures up to 1400 degrees, utilizing 0Cr27AI7Mo2 resistance wire. This configuration can handle short-term exposure to 1250 degrees with a robust steel jade porcelain support frame. The outer sleeve, an Fe Ni CrAI Re alloy, excels in oxidation resistance, enduring prolonged operation at 1300 degrees in oxidizing atmospheres, with short-term resistance at 1360 degrees. Ideal for challenging environments featuring high temperature, low oxygen, and SC presence.
