The heart of the Leader Heating Electric Radiant Tube is ingeniously crafted from U-shaped, axially arranged end welded resistance wires and ceramic support frames. With an open design, the heating core is unshielded by the outer protective sleeve, ensuring excellent heat dissipation. This radiant marvel is rated to perform at an impressive 1000 degrees Celsius, utilizing resistance wire materials such as Cr20Ni80 or 0Cr21AI6Nb. The outer surface can endure a commanding 1200 degrees, making it ideal for intensive applications. Crafted for high durability, the support frame boasts high alumina ceramic components. The outer protective sleeve is a masterpiece of engineering, featuring cold drawn seamless thin-walled heat-resistant steel pipes made of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, known for their superior high-temperature oxidation resistance and remarkable high-temperature creep strength. This stellar design is built with a high safety factor in mind. For the ultimate performance, the radiant tube's working temperature scales up to 1200 degrees, with the resistance wire material 0Cr27AI7Mo2. Surface temperatures can ascend to a blistering 1400 degrees, with short bursts reaching up to 1250 degrees. The support frame, a robustly constructed steel jade porcelain, pairs with a cold drawn seamless thin-walled heat-resistant steel sleeve made from Fe Ni CrAI Re alloy. This sleeve excels in oxidation resistance, operating long-term at 1300 degrees and short-term at 1360 degrees, perfect for high-temperature, low oxygen partial pressure, and SC containing environments.
