Introducing our advanced electric heating radiant tube technology, designed with precision and efficiency. The core features U-shaped, end-welded resistance wires, expertly supported by robust ceramic frames, ensuring optimal heat dissipation without protective shielding interference. Operating at a rated temperature of 1000 degrees, the resistance wire is composed of high-quality Cr20Ni80 or 0Cr21Al6Nb materials, achieving surface temperatures soaring to 1200 degrees. Crafted from high alumina ceramics, the support frame enhances durability. Enclosed in a seamless, cold-drawn thin-walled heat-resistant steel pipe of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this tube offers remarkable high-temperature oxidation resistance, exceptional high-temperature creep strength, and robust carburizing resistance. Engineered with a high safety factor, the tube's working temperature extends to 1200 degrees with the 0Cr27Al7Mo2 resistance wire, capable of surface temperatures reaching 1400 degrees. Its maximum short-term operating temperature peaks at 1250 degrees, supported by steel jade porcelain frames. The outer sleeve, forged from Fe Ni CrAl Re alloy, excels in oxidation resistance, performing efficiently at 1300 degrees Celsius in oxidizing atmospheres, and demonstrating short-term resilience at 1360 degrees Celsius. Ideal for high-temperature environments with low oxygen pressure and sulfur-containing conditions.
