The core of our electric heating radiant tube is ingeniously crafted with U-shaped, axially-aligned end welded resistance wires supported by robust ceramic frames. The design ensures unmatched heat dissipation as there is no barrier between the core and its outer protective sleeve. It proudly boasts a rated operational temperature of 1000°C, employing resistance wires made from superior Cr20Ni80 or 0Cr21AI6Nb materials. The surface can endure up to a sizzling 1200°C. The exceptional build allows it to peak at 1000°C for constant use, utilizing high alumina ceramic components for the support frame. Encased in a cold-drawn, seamless, thin-walled heat-resistant steel pipe crafted from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, its resistance to high-temperature oxidation and carburizing is remarkable. The safety factor in its design and material selection is commendably high. Moreover, our tubes can achieve a rated working temperature of 1200°C with resistance wires of 0Cr27AI7Mo2, the surface rising to an impressive 1400°C. For short-term applications, it withstands up to 1250°C, supported by steel jade porcelain frames. Its outer sheath, composed of Fe Ni CrAI Re alloy, offers unparalleled oxidation resistance, capable of enduring 1300°C for extended periods, and even short bursts up to 1360°C. This makes it ideal for high-temperature, low oxygen, and sulfur compound-rich settings.
