Delve into the cutting-edge design of the electric heating radiant tube, where the core brilliance lies in its U-shaped axially arranged end welded resistance wires, seamlessly supported by ceramic frames. A marvel of engineering, this tube is free from shielding barriers, allowing for superior heat dissipation. Boasting a rated working temperature of 1000 degrees, the resistance wire is crafted from either Cr20Ni80 or 0Cr21AI6Nb, with a surface working temperature soaring to 1200 degrees. When constructed with these materials, this radiant tube reaches a peak operating temperature of 1000 degrees, supported by high alumina ceramic components. The outer protective sleeve is a cold-drawn seamless thin-walled heat-resistant steel pipe, made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, delivering outstanding high-temperature oxidation resistance and resilience against carburizing. With a design founded on a high safety factor, the tube can achieve rated working temperatures of 1200 degrees, incorporating resistance wires of 0Cr27AI7Mo2 to reach surface temperatures of 1400 degrees. The maximum short-term working temperature extends to 1250 degrees, supported by steel jade porcelain frames. Encapsulated in a Fe Ni CrAI Re alloy cold-drawn seamless thin-walled pipe, this tube excels in oxidation resistance, enduring long-term operation at 1300 degrees Celsius in oxidizing atmospheres, and briefly withstanding up to 1360 degrees. Perfectly suited for environments with high temperatures, low oxygen pressure, and SC presence.
