U-shaped radiant tube is a radiant tube that ensures the controllability of the atmosphere in the furnace.
Radiant tubes are widely used in heating furnaces and are the main heating elements of heating furnaces.
At present, radiant tubes are mainly divided into two categories: gas radiant tubes and electric heating radiant tubes.
The thermal efficiency of gas-fired radiant tubes is about twice that of electrically heated radiant tubes. Therefore, gas radiant tubes are the development direction of radiant tubes in the future.
The heat energy of the heating furnace is usually provided by combustible gases such as natural gas, but the harmful gases produced by the combustible gas during the combustion process will destroy the environment required for heat treatment in the furnace.
Commonly used U-shaped radiant tube materials are 1.4848, 1.4849, 2.4879
