The heating core of our cutting-edge electric heating radiant tube is meticulously crafted from U-shaped axially arranged end-welded resistance wires, nestled within robust ceramic support frames. Uniquely designed without any shielding between the inner core and the outer protective sleeve, it boasts exceptional heat dissipation capabilities. This marvel operates at a rated temperature of 1000 degrees, using premium resistance wire materials like Cr20Ni80 or 0Cr21AI6Nb, achieving a remarkable surface temperature of up to 1200 degrees. Our radiant tube's engineering ensures a maximum working temperature of 1000 degrees, fortified by high alumina ceramic parts in its support frame. The outer sleeve, made from cold-drawn seamless thin-walled heat-resistant steel, employs materials such as 1Cr25Ni20Si2 or 1Cr25Ni35Si2, renowned for their outstanding high-temperature oxidation resistance, impressive creep strength, and carburizing resistance. Our meticulous design and material selection ensure a high safety factor, offering a rated working temperature of up to 1200 degrees with resistance wire 0Cr27AI7Mo2. The tube's surface can withstand 1400 degrees, with short-term peaks of 1250 degrees, supported by resilient steel jade porcelain. Encased in a superior Fe Ni CrAI Re alloy sleeve, it excels in oxidation resistance, operating reliably at 1300 degrees Celsius in oxidative environments and enduring short-term exposure to 1360 degrees. This product is ideal for high-temperature, low-oxygen, and sulfur-containing atmospheres.
