The heart of our electric heating radiant tube is ingeniously crafted from U-shaped, end welded resistance wires, elegantly supported by ceramic frames. This innovative design ensures excellent heat dissipation, with no barriers between the core and protective sleeve. Engineered for robustness, the radiant tube operates at a rated working temperature of 1000 degrees Celsius, thanks to high-performance resistance wires made from Cr20Ni80 or 0Cr21AI6Nb. The surface temperature can soar to an impressive 1200 degrees. The cutting-edge materials allow the radiant tube to reach a maximum working temperature of 1000 degrees, supported by high alumina ceramic components. Encased in a meticulously engineered cold drawn seamless thin-walled heat-resistant steel pipe, made of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this product exhibits outstanding high-temperature oxidation resistance, strength, and carburizing resistance. Designed with a high safety factor, our radiation tube boasts a rated working temperature of 1200 degrees, utilizing 0Cr27AI7Mo2 resistance wires. The surface can withstand up to 1400 degrees, with the potential for maximum short-term operation at 1250 degrees, supported by the resilience of steel jade porcelain. The outer sleeve, crafted from a Fe Ni CrAI Re alloy, offers superior oxidation resistance, capable of withstanding prolonged exposure to 1300 degrees Celsius in oxidizing environments, and short-term resistance up to 1360 degrees. Ideal for high-temperature, low oxygen, and sulfur-containing atmospheres, our electric radiant tubes promise unparalleled performance.
