Product Description

The core component of our electric heating radiant tube showcases an advanced design, featuring U-shaped, end-welded resistance wires meticulously aligned axially, supported by robust ceramic frames. This design ensures outstanding heat dissipation as there is no shielding between the core and its protective sleeve. The tube operates efficiently at a rated temperature of 1000 degrees, utilizing Cr20Ni80 or 0Cr21AI6Nb resistance wires, reaching surface temperatures of up to 1200 degrees. Crafted for optimal performance, the high alumina ceramic support frame and the outer cold-drawn seamless thin-walled heat-resistant steel pipe confer exceptional high-temperature oxidation resistance and creep strength under demanding conditions. Our design boasts a superior safety margin, with the radiation tube also available in materials allowing for a rated temperature of 1200 degrees and maximum short-term exposure at 1250 degrees using 0Cr27AI7Mo2 wires. Encased in a Fe Ni CrAI Re alloy sleeve, these tubes withstand long-term exposure to 1300 degrees Celsius in oxidizing atmospheres and transient resistance at 1360 degrees, perfect for high-temperature, low-oxygen, and SC-rich environments.
