Delve into the meticulously engineered heating core of our electric heating radiant tube, which seamlessly integrates U-shaped axially aligned end welded resistance wires with robust ceramic support frames. This innovative design, devoid of inner core shielding from the outer protective sleeve, ensures superior heat dissipation. With a rated working temperature of a formidable 1000 degrees, our radiant tube employs resistance wires crafted from Cr20Ni80 or 0Cr21AI6Nb, boasting a surface working temperature soaring to 1200 degrees. The pinnacle of its performance is a maximum working temperature of 1000 degrees, supported by high alumina ceramic components. The outer protective sleeve, a masterpiece of cold-drawn seamless thin-walled heat-resistant steel pipe, is composed of 1Cr25Ni20Si2 or 1Cr25Ni35Si2, renowned for its stellar high-temperature oxidation resistance, impressive high-temperature creep strength, and excellent carburization resistance. Thoughtfully selected design materials bestow a high safety factor upon this radiant tube, with a rated temperature of 1200 degrees and resistance wire of 0Cr27AI7Mo2. It can achieve a surface working temperature of 1400 degrees, with a remarkable short-term capability of 1250 degrees. Encased in a protective sleeve of cold-drawn seamless thin-walled heat-resistant steel pipe, made from Fe Ni CrAI Re alloy, this tube exhibits exceptional oxidation resistance, performing diligently at 1300 degrees Celsius and demonstrating short-term resilience at 1360 degrees Celsius. Ideal for operation in high-temperature, low oxygen partial pressure, and sulfur and carbon containing environments.
