The heating core of this sophisticated electric heating radiant tube is ingeniously crafted with U-shaped axially arranged end welded resistance wires, elegantly supported by durable ceramic frames. Enjoy unparalleled heat dissipation as there's no barrier between the inner core and the outer protective sleeve. Engineered to perfection, this radiant tube boasts a rated working temperature soaring up to 1000 degrees, thanks to its robust resistance wire options: Cr20Ni80 or 0Cr21AI6Nb. Experience heightened performance with a surface working temperature reaching 1200 degrees. Constructed using high alumina ceramic parts, the support frame ensures steadfast reliability. The outer protective sleeve, a masterpiece of engineering, is a cold drawn seamless thin-walled heat-resistant steel marvel, made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offering remarkable high-temperature oxidation resistance and a commendable resistance to carburizing. Designed with a formidable safety factor, this tube excels with a rated working temperature of 1200 degrees, featuring resistance wires of 0Cr27AI7Mo2. Its surface can attain a remarkable 1400 degrees, with maximum short-term capabilities of 1250 degrees, supported by the robust steel jade porcelain frame. Encased in an Fe Ni CrAI Re alloy cold drawn seamless protective sleeve, it promises exceptional oxidation resistance, thriving in conditions up to 1300 degrees Celsius and enduring short-term exposure at 1360 degrees Celsius. Perfectly suited for challenging environments of high temperature, low oxygen partial pressure, and SC containing atmospheres.
