Radiant tubes

Radiant tubes that we can product including U-type, W-Type, 0-Type, P-type, L-Type, S-Type, Straight-type and Electric.

What are radiant tubes ?

Radiant tube is a tube extending straight from the center in all directions. The purpose of the radiant tube is to transfer heat to the load by radiation, heat transferred to other workpieces after load heating. It is used in the heating furnace and is the main heating element of the heating furnace. At present, there are two kinds of radiant tubes: gas radiant tubes and electric heating radiant tubes.

Not only in the industrial industry, radiant tubes are widely used in other fields, such as metallurgical industry, electrical industry, ceramic industry and so on.

Why are they Used ?

  • It can work at high temperature
  • Compared with other heating methods, radiant tube heating is more uniform
  • Any shape and size ensures that the open flame can be isolated from the material

Work enviroment

Radiant tube operate at high temperatures averaging 800-1200 ℃

Most are used for indirect heating in furnaces. 

Tubes Process

Centrifugal casting and spun casting method for tube sections 

Investment casting or sand casting for the bends, hangers, welding and machining
