The core marvel of our electric heating radiant tube is a sophisticated assembly of U-shaped, axially arranged end welded resistance wires, embraced by robust ceramic support structures. Ingeniously designed to eliminate any shielding between the inner core and the outer protective sleeve, this masterpiece ensures superior heat dissipation. Operating at a formidable rated temperature of up to 1000 degrees, crafted with high-grade Cr20Ni80 or 0Cr21AI6Nb resistance wire, the surface temperature marvelously peaks at 1200 degrees. Our meticulous selection elevates the maximum operational temperature to 1000 degrees, supported by high alumina ceramic components, cloaked by a cold drawn seamless thin-walled protective sleeve of 1Cr25Ni20Si2 or 1Cr25Ni35Si2 steel. Renowned for its exceptional high-temperature oxidation resistance, remarkable creep strength at elevated temperatures, and resilience against carburizing, it delivers unparalleled safety and reliability. In an upgraded version, experience a rated working temperature reaching 1200 degrees with resistance wire crafted from 0Cr27AI7Mo2, achieving surface temperatures soaring to 1400 degrees. For short bursts, the tube withstands an extraordinary 1250 degrees, supported by steel jade porcelain frames. Encased in a protective sleeve of Fe Ni CrAI Re alloy, it boasts high oxidation resistance, enduring long-term at 1300 degrees in oxidizing environments, and short-term ability at 1360 degrees. Perfectly designed for high-temperature, low oxygen, and SC containing atmospheres.
