辐射管是一种广泛应用于加热炉中的重要设备，其主要功能是将热量从中心向各个方向沿直线延伸的管道传递到指定或非指定的位置。根据不同的工作原理和材料，辐射管可以分为燃气辐射管和电加热辐射管两大类。

       Radiation tube is an important e widely used in heating furnace, its main function is to transfer heat from the center to all directions along the straight line of the pipeline to the designated or non-designated location. According to different working principles and materials, radiant tubes can be divided into gas radiant tubes and electric heating radiant tubes.
