The heart of our electric heating radiant tube is expertly crafted with U-shaped axially arranged end welded resistance wires and robust ceramic support frames. This innovative design boasts an unobstructed core within its outer protective sleeve, ensuring exceptional heat dissipation. Operating at a rated temperature of 1000 degrees, the resistance wire is crafted from top-tier Cr20Ni80 or 0Cr21AI6Nb materials, pushing the surface working temperature up to a remarkable 1200 degrees. For enhanced performance, the electric radiation tube can achieve a maximum working temperature of 1000 degrees, supported by high alumina ceramic components. Encased in a cold drawn seamless thin-walled heat-resistant steel pipe, made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this material provides outstanding high-temperature oxidation resistance, robust creep strength, and carburizing resistance. Designed with meticulous precision, this radiation tube's material selection promises a high safety factor. With an upgraded rated working temperature of 1200 degrees and resistance wires of 0Cr27AI7Mo2, the surface temperature can escalate to 1400 degrees. Short-term working conditions allow for temperatures as high as 1250 degrees, with the support frame constructed from steel jade porcelain. Its outer protective sleeve is reinforced with Fe Ni CrAI Re alloy, endowed with superior oxidation resistance, capable of enduring 1300 degrees Celsius for extended periods in oxidizing atmospheres, and resisting short-term oxidation at 1360 degrees Celsius. It is perfectly suited for high-temperature, low oxygen partial pressure, and SC containing environments.
