The innovative core of our Leader Electric Heater's radiant tube is crafted with precision, featuring U-shaped, axially arranged end-welded resistance wires supported by robust ceramic frames. This dynamic design ensures excellent heat dissipation, free from any shielding between the core and its protective sleeve. With a rated working temperature of 1000 degrees Celsius, our premium-grade resistance wires, made from Cr20Ni80 or 0Cr21AI6Nb, guarantee outstanding performance. The surface working temperature soars to 1200 degrees, ensuring powerful heating capabilities. Crafted with high alumina ceramic support frames, this electric radiation tube excels in durability. Its outer protective sleeve, a cold-drawn seamless thin-walled heat-resistant steel pipe made of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offers exceptional high-temperature oxidation resistance and strength against creep and carburization. Designed for safety and reliability, the tube's rated working temperature reaches 1200 degrees, with surface temperatures up to 1400 degrees, and short-term capabilities of 1250 degrees. The support frame from steel jade porcelain reinforces its robustness. The protective sleeve, crafted from Fe Ni CrAI Re alloy, withstands long-term operation at 1300 degrees Celsius in oxidizing environments and resists short-term oxidation at 1360 degrees. Ideal for high-temperature applications, even in low oxygen and sulfur-containing settings.
