The heart of our advanced electric heating radiant tube is crafted with precision, featuring U-shaped axially aligned end-welded resistance wires and ceramic support frames. This design ensures excellent heat dissipation, as there is no barrier between the inner core and the outer protective sleeve. The rated operating temperature of the electric radiant tube soars to 1000 degrees Celsius, with resistance wires made from Cr20Ni80 or 0Cr21AI6Nb materials. It can achieve a surface operating temperature of up to 1200 degrees Celsius. The exceptional electric radiant tube crafted from these materials boasts a maximum working temperature of 1000 degrees Celsius, supported by high alumina ceramic parts. Encased in a cold drawn seamless thin-walled heat-resistant steel pipe, made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, the outer protective sleeve offers remarkable high-temperature oxidation resistance, robust high-temperature creep strength, and a certain resistance to carburizing. This meticulous design and material selection endow our radiant tube with an exceptional safety factor. For higher performance, we offer radiant tubes rated at 1200 degrees Celsius, utilizing 0Cr27AI7Mo2 resistance wire that can withstand surface temperatures up to 1400 degrees Celsius. With a maximum short-term operational limit of 1250 degrees Celsius, supported by steel jade porcelain frames, and an outer protective sleeve made from a cold drawn Fe Ni CrAI Re alloy, these tubes exhibit superior oxidation resistance. Capable of enduring continuous operation at 1300 degrees Celsius in oxidizing atmospheres, they also offer short-term resistance at 1360 degrees Celsius. Perfectly engineered for high temperature, low oxygen partial pressure, and SC containing environments, our radiant tubes stand as the epitome of engineering excellence.
