The heating core of our robust electric heating radiant tube is ingeniously crafted with U-shaped axially arranged end-welded resistance wires, supported by ceramic support frames to ensure excellence in heat distribution. The absence of shielding between the inner core and outer protective sleeve enhances heat dissipation remarkably. Designed for a rated working temperature of 1000 degrees Celsius, the resistance wire material is either Cr20Ni80 or 0Cr21AI6Nb, while the surface working temperature impressively reaches 1200 degrees. The exceptional materials allow the electric radiation tube to withstand maximum working temperatures of up to 1000 degrees, supported by high alumina ceramic components that ensure stability and durability. Encased in a cold drawn seamless thin-walled heat-resistant steel pipe, made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, this remarkable material offers unparalleled high-temperature oxidation resistance, superior creep strength, and notable carburizing resistance. With a high safety factor in its design and material selection, the tube further boasts a rated working temperature increase to 1200 degrees, achieved with 0Cr27AI7Mo2 resistance wire. The surface working temperature can spike to an impressive 1400 degrees, and the tube can endure short-term temperatures of 1250 degrees. Supported by steel jade porcelain frames, the outer protective sleeve's Fe Ni CrAL Re alloy composition ensures long-term functionality at 1300 degrees Celsius in oxidizing environments, withstanding brief oxidation resistance at 1360 degrees Celsius. Perfectly adapted for high-temperature environments with low oxygen partial pressure and SC presence, this innovative electric radiation tube is engineered for industrial excellence.
