The cutting-edge heating core of the Leader Heating Electric Radiant Tube is ingeniously crafted with U-shaped, axially arranged end-welded resistance wires and robust ceramic support frames, ensuring unmatched thermal performance. Unlike conventional designs, our radiant tube has no shielding between the inner core and the outer protective sleeve, resulting in exceptional heat dissipation. This innovative electric radiation tube operates at a rated temperature of up to 1000 degrees, utilizing Cr20Ni80 or 0Cr21AI6Nb resistance wires. The surface working temperature impressively reaches 1200 degrees. By leveraging high alumina ceramic parts for the support frame, the radiant tube boasts extraordinary durability. The sleek outer protective sleeve is made from a cold drawn, seamless, thin-walled heat-resistant steel pipe consisting of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offering superior high-temperature oxidation resistance, commendable high-temperature creep strength, and notable carburizing resistance. Its meticulous design and material selection ensure a high safety factor, allowing the rated working temperature to soar to 1200 degrees with 0Cr27AI7Mo2 resistance wires. Amazingly, the surface working temperature can peak at 1400 degrees, and the radiant tube's maximum short-term working temperature achieves 1250 degrees. For added resilience, the support frame is fashioned from steel jade porcelain. The outer protective sleeve is refined from a cold drawn seamless thin-walled heat-resistant steel pipe utilizing Fe Ni CrAI Re alloy, providing enhanced oxidation resistance. It can consistently function in an oxidizing environment at 1300 degrees Celsius and withstand short-term oxidation resistance up to 1360 degrees Celsius. Suitable for challenging high-temperature, low oxygen partial pressure, and sulfur-containing conditions.
