The innovative heating core of our electric heating radiant tube is meticulously crafted with U-shaped axially arranged end welded resistance wires supported by robust ceramic frames. This design ensures optimal heat dissipation, as there is no shielding between the core and the outer protective sleeve. The electric radiation tube boasts an impressive rated working temperature of 1000 degrees, utilizing resistance wires made from Cr20Ni80 or 0Cr21AI6Nb. The surface temperature can reach a formidable 1200 degrees. Crafted from high alumina ceramic parts, the support frame enhances durability. Meanwhile, the external protective sleeve features a cold drawn seamless thin-walled heat-resistant steel pipe crafted from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, known for its superior high-temperature oxidation resistance, remarkable creep strength, and resistance to carburization. Safety is paramount, with the tube's design emphasizing reliability. For even higher demands, the electric radiation tube can reach a rated working temperature of 1200 degrees, employing resistance wires made from 0Cr27AI7Mo2. The surface temperature can ascend to 1400 degrees, with a maximum short-term capacity of 1250 degrees, supported by steel jade porcelain. The outer sheath, an Fe Ni CrAI Re alloy, excels in oxidation resistance, enduring prolonged exposure at 1300 degrees Celsius in oxidizing environments and short-term resistance up to 1360 degrees Celsius. Perfectly suited for high-temperature, low oxygen, and sulfur-containing conditions.
