Crafted with precision, the heating core of our electric heating radiant tube embodies advanced U-shaped axially arranged end-welded resistance wires, expertly supported by durable ceramic frames. With no shielding between the inner core and the outer protective sleeve, our design ensures exceptional heat dissipation. Achieving a rated working temperature of 1000 degrees, the resistance wire is crafted from superior materials like Cr20Ni80 or 0Cr21AI6Nb, allowing the surface to reach 1200 degrees. Our choice of high alumina ceramic parts for the support frame underlines our commitment to quality. The outer protective sleeve is constructed from a cold-drawn seamless thin-walled heat-resistant steel pipe, available in 1Cr25Ni20Si2 or 1Cr25Ni35Si2, known for their high-temperature oxidation resistance and structural integrity. Designed for safety, our electric radiation tube can achieve a rated working temperature of 1200 degrees with resistance wire material 0Cr27AI7Mo2, supporting surface temperatures of up to 1400 degrees. For short-term performance, it withstands up to 1250 degrees, featuring a cold-drawn seamless thin-walled pipe made from Fe Ni CrAI Re alloy, renowned for its high oxidation resistance and operational endurance up to 1300 degrees in oxidizing conditions. This makes it ideal for challenging environments with high temperatures, low oxygen, and SC presence.
