Crafted for superior performance, the electric heating radiant tube heating core is ingeniously constructed with U-shaped, axially aligned end-welded resistance wires nestled within ceramic support frames. Designed for optimal heat dissipation, it features no shielding between the inner core and the outer protective sleeve. The electric radiation tube is engineered for rigorous conditions with a rated working temperature of 1000 degrees, composed of Cr20Ni80 or 0Cr21AI6Nb resistance wire, allowing surface temperatures to ascend to 1200 degrees. This state-of-the-art material ensures that the electric radiation tube withstands peak temperatures of 1000 degrees. Strength is further enhanced by high alumina ceramic support frames. The outer protective sleeve, a masterpiece of cold-drawn seamless thin-walled heat-resistant steel pipe, is fashioned from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, delivering remarkable high-temperature oxidation resistance, elevated creep strength, and anti-carburization properties. Meticulous design and material choices ensure an elevated safety margin. A variant of the radiation tube, rated for 1200 degrees, features 0Cr27AI7Mo2 resistance wire, enabling surface operation up to 1400 degrees. This high-performance electric radiation tube can briefly endure 1250 degrees, supported by steel jade porcelain frames. Encased in an Fe Ni CrAI Re alloy sleeve, it exhibits formidable oxidation resistance, sustaining prolonged use at 1300 degrees under oxidizing atmospheres and brief exposure at 1360 degrees. Ideal for high-temperature, low-oxygen, and SC-environments.
