Radiant tube is commonly used in industry equipment, plays an important role in the process of the operation of the industrial furnace, can people who for radiant tube also is not very understanding, today with everybody to know about the part of the radiant tube as well as their respective role.Radiant tube electric performance is stable, high thermal efficiency, heat up quickly, small thermal hysteresis, good heat transfer performance, heat utilization Gordon advantages, and installation, testing and maintenance, all carried out outside the furnace, do not need to stop the furnace cooling temperature for repair or replacement of electric heating device.So both in the industrial sector, and in some civil equipment are used to it.Today, industrial progress, for the requirement of equipment is higher, the radiant tube market demand is becoming more and more high, to improve the quality of the radiant tube, must be from the composition fluctuation kongfu, only with the performance of the parts is good, can improve the performance of radiant tube.
