Product Description

The heating core of our electric heating radiant tube is ingeniously crafted with U-shaped, axially arranged end-welded resistance wires, supported by robust ceramic frames. With no internal shielding, it ensures optimal heat dissipation. Boasting a rated working temperature of 1000 degrees Celsius, the resistance wire is made from premium Cr20Ni80 or 0Cr21AI6Nb, while the surface can handle up to 1200 degrees Celsius. Our design, featuring high alumina ceramic support frames and a cold drawn, seamless thin-walled heat-resistant steel pipe crafted from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, prioritizes safety and durability. This material excels in high-temperature oxidation resistance and offers impressive strength under extreme temperatures. For enhanced performance, our radiation tubes with 0Cr27AI7Mo2 resistance wire reach a rated temperature of 1200 degrees and a maximum short-term operation at 1250 degrees Celsius. The steel jade porcelain support frame and Fe Ni CrAI Re alloy outer sleeve ensure resilience against oxidation, operating efficiently in oxidizing atmospheres up to 1300 degrees, withstanding short-term peaks at 1360 degrees. This makes it ideal for high-temperature, low-oxygen, and sulfur-containing environments.
