The core of our state-of-the-art electric heating radiant tube is crafted with precision, featuring U-shaped, end-welded resistance wires supported by ceramic frames. Designed for maximum heat dissipation, the absence of shielding between the core and outer protective sleeve ensures efficient thermal conduction. Capable of working at a rated temperature of 1000 degrees, the resistance wire is composed of either Cr20Ni80 or 0Cr21AI6Nb, with the surface achieving up to 1200 degrees. For enhanced durability, high-alumina ceramic parts form the support frame, while the outer sleeve is made from a cold-drawn seamless thin-walled heat-resistant steel pipe, specifically 1Cr25Ni20Si2 or 1Cr25Ni35Si2, renowned for its superior high-temperature oxidation resistance and creep strength. Our design prioritizes safety, allowing the tube to reach a remarkable 1200 degrees with 0Cr27AI7Mo2 resistance wire. The surface can soar to 1400 degrees, and in short bursts, achieve 1250 degrees with steel jade porcelain support. Encased in an Fe Ni CrAI Re alloy sleeve, it endures prolonged exposure to 1300 degrees in oxidizing conditions, resisting oxidation even up to 1360 degrees. Ideal for high-temperature, low-oxygen, and SC-rich environments, this tube epitomizes reliability and robust performance.
