The cutting-edge heating core of our electric radiant tube features meticulously engineered U-shaped, axially arranged resistance wires end-welded to ceramic support frames, ensuring optimal performance. With no shielding between the inner core and the outer protective sleeve, our design ensures superior heat dissipation. Our electric radiation tube boasts a rated working temperature of a substantial 1000 degrees Celsius, crafted with high-quality resistance wire materials such as Cr20Ni80 or 0Cr21AI6Nb, enabling surface working temperatures up to 1200 degrees. The maximum working potential reaches an impressive 1000 degrees, with support frames composed of high alumina ceramic parts. The outer protective sleeve is crafted from cold drawn seamless thin-walled heat-resistant steel pipe, using materials like 1Cr25Ni20Si2 or 1Cr25Ni35Si2, known for their remarkable high-temperature oxidation resistance and creep strength. This meticulous design ensures a high safety factor. For more demanding applications, our electric radiation tube is engineered with a rated working temperature of 1200 degrees, using resistance wire of 0Cr27AI7Mo2, capable of reaching surface temperatures as high as 1400 degrees. The pinnacle of its short-term working temperature is 1250 degrees, leveraging the strength of steel jade porcelain support frames. The outer sleeve, made of Fe Ni CrAI Re alloy, offers exceptional oxidation resistance and can maintain integrity in oxidizing environments at 1300 degrees Celsius and withstand short-term exposure up to 1360 degrees. Ideal for high-temperature, low-oxygen, and SC-containing settings.
