Experience unparalleled heating efficiency with our advanced electric heating radiant tube core, meticulously crafted with precision. Our U-shaped axially arranged end welded resistance wires and ceramic support frames ensure optimal heat dissipation, free from shielding obstacles, delivering excellent results. Designed to withstand demanding conditions, the electric radiation tube boasts a rated working temperature of 1000 degrees Celsius, utilizing the finest Cr20Ni80 or 0Cr21AI6Nb resistance wire material. Revel in the robust performance as the surface working temperature reaches a remarkable 1200 degrees Celsius. The support frame's high alumina ceramic composition ensures durability, complemented by a cold drawn seamless thin-walled heat-resistant steel pipe outer sleeve, made from 1Cr25Ni20Si2 or 1Cr25Ni35Si2, offering superior high-temperature oxidation resistance, enhanced creep strength, and carburizing resistance. This meticulously selected material and design promise a high safety factor. For even more demanding applications, the electric radiation tube's rated working temperature escalates to 1200 degrees, with the resistance wire material upgraded to 0Cr27AI7Mo2, achieving an exceptional surface working temperature of 1400 degrees. In extreme short-term conditions, the tube withstands up to 1250 degrees Celsius, with a support frame of steel jade porcelain. The outer sleeve, crafted from Fe Ni CrAI Re alloy, boasts unrivaled high oxidation resistance, perfect for long-term use at 1300 degrees Celsius in oxidizing atmospheres and short-term at 1360 degrees Celsius, adept at thriving in high temperature, low oxygen partial pressure, and sulfur-containing environments.
