The core of our electric heating radiant tube magnificently combines U-shaped end-welded resistance wires with ceramic support frames. With an unobstructed design between the core and its protective sleeve, it boasts excellent heat dissipation. Designed to endure a rated temperature of 1000 degrees, the resistance wires are crafted from either Cr20Ni80 or 0Cr21AI6Nb, with surface temperatures soaring to 1200 degrees. The tube's structure allows for a peak operation at 1000 degrees, supported by high alumina ceramic parts. Encased in a cold-drawn seamless thin-walled heat-resistant steel pipe, made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, it exhibits outstanding high-temperature oxidation resistance, creep strength, and carburization resistance. With a focus on safety and material excellence, this tube can sustain a working temperature of 1200 degrees, utilizing 0Cr27AI7Mo2 resistance wire to elevate surface temperatures to an impressive 1400 degrees. The short-term maximum operating temperature reaches 1250 degrees, with steel jade porcelain support frames, and is protected by a cold-drawn seamless thin-walled heat-resistant steel pipe crafted from Fe Ni CrAI Re alloy. This enables extended operation at 1300 degrees Celsius in oxidizing conditions, with enhanced short-term oxidation resistance up to 1360 degrees Celsius. Perfectly suited for high-temperature, low oxygen, and SC-laden environments.
