The highly efficient heating core of our Leader Electric Heater's radiant tube features an expertly crafted combination of U-shaped axially arranged end welded resistance wires, held in place by durable ceramic support frames. With no barriers between the inner core and its outer protective sleeve, optimal heat dissipation is ensured. Our electric radiation tube boasts a rated working temperature of an impressive 1000 degrees, using resistance wires made from Cr20Ni80 or 0Cr21AI6Nb. Remarkably, the surface working temperature can soar to 1200 degrees, making it ideal for demanding environments. For materials like these, the maximum working temperature reaches 1000 degrees, supported by high alumina ceramic parts. Encased in a cold-drawn seamless thin-walled heat-resistant steel pipe composed of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this construction excels with outstanding high-temperature oxidation resistance, high-temperature creep strength, and carburizing resistance. Designed with a high safety factor, the tube's rated working temperature can achieve 1200 degrees, utilizing 0Cr27AI7Mo2 resistance wire for an even higher surface temperature capacity of 1400 degrees. Short-term, this robust electric radiation tube can handle up to 1250 degrees, thanks to its steel jade porcelain support frame. Its cutting-edge outer protective sleeve, forged from Fe Ni CrAI Re alloy, delivers remarkable oxidation resistance, enduring long-term operation at 1300 degrees Celsius in oxidizing atmospheres and offering short-term protection at 1360 degrees Celsius. Perfectly suited for high-temperature, low-oxygen environments with sulfur and carbon.
