The core of our electric heating radiant tube is ingeniously designed with U-shaped, axially-aligned resistance wires welded at the ends, supported by durable ceramic frames. This advanced configuration, free from internal shielding, ensures excellent heat dissipation. Built to withstand the toughest conditions, the electric radiant tube's rated working temperature reaches an impressive 1000 degrees Celsius, utilizing robust resistance wires composed of Cr20Ni80 or 0Cr21AI6Nb. Our product can achieve a remarkable surface working temperature of 1200 degrees Celsius. The maximum operation temperature of our radiant tube can reach up to 1000 degrees due to the high-quality high alumina ceramic support frames. Encased in a cold-drawn, seamless, thin-walled heat-resistant steel pipe crafted from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, our outer protective sleeve boasts outstanding high-temperature oxidation resistance, exceptional creep strength, and resilience against carburizing environments. With a design prioritizing safety and material excellence, our radiant tube's rated temperature extends to 1200 degrees, using top-tier 0Cr27AI7Mo2 resistance wires. The surface temperature can soar to 1400 degrees, handling a maximum short-term working temperature of 1250 degrees. The support frame made from steel jade porcelain ensures sturdy reliability. The outer protective sleeve is engineered with Fe Ni CrAI Re alloy, offering superior oxidation resistance to function reliably at 1300 degrees Celsius in oxidizing atmospheres and short-term resilience at 1360 degrees Celsius. Ideal for high-temperature operations, low oxygen pressure, and environments with SC components.
