The heart of the High-Efficiency Heating Electric Radiant Tube by Leader is ingeniously engineered with U-shaped end welded resistance wires, complemented by ceramic support frames. Designed without any internal shielding, this ensures remarkable heat dissipation. Operable at a rated temperature of 1000 degrees, the tube boasts resistance wires made from Cr20Ni80 or 0Cr21AI6Nb, achieving an impressive surface working temperature of up to 1200 degrees. The robust construction allows the tube to withstand peak temperatures of 1000 degrees. High alumina ceramic supports further enhance durability, while the outer protective layer is crafted from cold-drawn, seamless, thin-walled heat-resistant steel, specifically 1Cr25Ni20Si2 or 1Cr25Ni35Si2, known for its superb high-temperature oxidation resistance and strong creep strength. This meticulous design ensures a high safety margin. Additionally, the tube can also be rated at 1200 degrees using 0Cr27AI7Mo2 resistance wires, reaching a phenomenal surface temperature of 1400 degrees, capable of enduring short-term peaks of 1250 degrees. Steel jade porcelain support frames and Fe Ni CrAI Re alloy sleeves offer exceptional oxidation resistance, operating steadily at 1300 degrees Celsius and enduring short-term exposure to 1360 degrees Celsius. Perfectly suited for challenging environments with high temperatures, low oxygen, and sulfuric conditions.
