The core element of our electric heating radiant tube is ingeniously crafted from U-shaped resistance wires, axially arranged and welded to perfection, supported by sturdy ceramic frames. This design ensures optimal heat dissipation, as there's no barrier between the inner core and the outer protective sleeve. Operating at a remarkable rated temperature of 1000 degrees, the resistance wire options include Cr20Ni80 or 0Cr21AI6Nb, capable of reaching surface temperatures of 1200 degrees. This premium construction allows the tube to operate safely at maximum temperatures of 1000 degrees, thanks to high alumina ceramic support frames. The protective outer sleeve, a seamless, thin-walled steel marvel made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offers exceptional high-temperature oxidation resistance, creep strength, and resistance to carburization. Our meticulously designed radiation tube boasts a robust safety factor, achieving a rated working temperature of 1200 degrees. With 0Cr27AI7Mo2 resistance wire, it can achieve surface temperatures up to 1400 degrees, and an impressive short-term peak of 1250 degrees. The support frame is crafted from durable steel jade porcelain, while the outer protective sleeve, an Fe Ni CrAI Re alloy, showcases unparalleled oxidation resistance, performing brilliantly at 1300 degrees Celsius in oxidizing environments and handling short-term exposure up to 1360 degrees. Perfectly suited for high-temperature, low oxygen, and SC-rich conditions.
