The heart of our electric heating radiant tube is ingeniously crafted with U-shaped axially arranged end welded resistance wires, supported by robust ceramic frames. With no shielding between the inner core and the outer protective sleeve, we guarantee excellent heat dissipation. Our radiant tube boasts a rated working temperature of 1000 degrees, utilizing resistance wires made from Cr20Ni80 or 0Cr21AI6Nb. The surface temperature can ascend to 1200 degrees, with the highest working capacity reaching 1000 degrees, all underpinned by high alumina ceramic support frames. Encased in a cold drawn seamless thin-walled heat-resistant steel pipe, composed of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, the material exemplifies superior high-temperature oxidation resistance and significant resistance to carburizing. Our design and material selection ensure an unparalleled safety factor. Rated at 1200 degrees, the resistance wire crafted from 0Cr27AI7Mo2 elevates surface temperatures to 1400 degrees, with a short-term max of 1250 degrees. The steel jade porcelain support frame and the Fe Ni CrAI Re alloy outer sleeve promise outstanding oxidation resilience, perfect for enduring operations up to 1300 degrees Celsius, withstanding short-term exposure to 1360 degrees, ideal for high-temperature, low oxygen, and SC environments.
