Dive into unparalleled efficiency with the cutting-edge heating core of our electric radiant tube heater, expertly constructed with U-shaped, axially arranged end welded resistance wires seamlessly mounted on robust ceramic support frames. By eliminating any shielding between the inner core and the outer protective sleeve, heat dissipation is optimized to perfection. The electric radiation tube boasts an impressive rated working temperature of 1000 degrees, crafted from high-performance resistance wire materials such as Cr20Ni80 or 0Cr21AI6Nb, with its surface working temperature soaring to 1200 degrees. The maximum operational temperature reaches a remarkable 1000 degrees, supported by high alumina ceramic components. Enveloped in a cold-drawn seamless thin-walled heat-resistant steel pipe composed of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this material exhibits exceptional high-temperature oxidation resistance, superior high-temperature creep strength, and robust carburizing resistance. Designed for ultimate safety, our radiation tube material selection ensures reliability at a rated working temperature of 1200 degrees, using 0Cr27AI7Mo2 resistance wire. Experience elevated performance with surface temperatures reaching up to 1400 degrees. The tube's short-term working temperature peaks at 1250 degrees, complemented by a support frame crafted from steel jade porcelain. Featuring an outer protective sleeve made from cold-drawn seamless thin-walled heat-resistant Fe Ni CrAI Re alloy, it offers unmatched high oxidation resistance. Engineered to withstand prolonged exposure at 1300 degrees Celsius within oxidizing environments, it's fortified for short-term resistance up to 1360 degrees Celsius, making it ideal for high-temperature, low-oxygen partial pressure, and SC containing conditions.
