The heart of our electric heating radiant tube is ingeniously crafted with U-shaped, axially aligned end-welded resistance wires, expertly supported by ceramic frames. Enjoy excellent heat dissipation, with no barriers between the inner core and the protective sleeve. The rated working temperature reaches a robust 1000 degrees, using Cr20Ni80 or 0Cr21AI6Nb resistance wire. Our surface working temperature impressively peaks at 1200 degrees. Constructed with high-alumina ceramic parts, the support frame ensures durability, while the outer protective sleeve, made from high-quality 1Cr25Ni20Si2 or 1Cr25Ni35Si2 seamless thin-walled heat-resistant steel pipe, is engineered to withstand high-temperature oxidation, exhibiting superior high-temperature creep strength and carburizing resistance. Designed with a high safety factor, our radiant tube's rated working temperature elevates to 1200 degrees with 0Cr27AI7Mo2 resistance wire, and the surface working temperature surges to 1400 degrees. The maximum short-term working temperature touches 1250 degrees. The steel jade porcelain support frame adds unrivaled strength, while the protective sleeve, crafted from Fe Ni CrAI Re alloy, excels in oxidation resistance, thriving at 1300 degrees Celsius in oxidizing atmospheres and showing resilience at 1360 degrees Celsius in short-term conditions. Ideal for high-temperature, low-oxygen partial pressure, and SC environments.
