The heart of our electric heating radiant tube is ingeniously designed, consisting of meticulously arranged U-shaped end-welded resistance wires supported by robust ceramic frames. Uniquely, there is no barrier between the inner core and its protective sleeve, facilitating exceptional heat dissipation. Engineered for excellence, the electric radiation tube endures a rated working temperature of 1000 degrees, with resistance wires crafted from Cr20Ni80 or 0Cr21AI6Nb materials. The surface working temperature impressively reaches up to 1200 degrees. For heightened performance, the radiation tube constituents allow it to operate at a peak temperature of 1000 degrees, thanks to the high alumina ceramic support frames. Encased in a specially designed cold-drawn, seamless, thin-walled heat-resistant steel pipe, crafted of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this apparatus offers superior high-temperature oxidation resistance, remarkable creep strength, and a notable resistance to carburizing, ensuring reliability and safety. The sophisticated design and meticulous material selection boast a high safety factor, with the rated working temperature soaring to 1200 degrees. Utilizing 0Cr27AI7Mo2 resistance wire, the surface temperature can ascend to an astounding 1400 degrees. For short-term applications, the maximum working temperature reaches 1250 degrees, supported by steel jade porcelain frames. Featuring an outer sleeve of Fe Ni CrAI Re alloy, this remarkable tube showcases high oxidation resistance, capable of enduring long-term operations at 1300 degrees Celsius in oxidizing environments and offering short-term resilience at 1360 degrees Celsius. Perfectly suited for challenging conditions such as high temperature, low oxygen partial pressure, and sulfur-containing environments.
