Product Description

Electrical Radiant Tubes with Electric Ceramic Heating Elements

Product Description

 

Radiant Tube	Radiant tubes are used in industry for different heat treatment processes with a protective gas atmosphere in steel and nonferrous metal industry. There are different shapes during application, such as: - Single-ended type (I type) Radiant Tube, - P type Radiant Tube, - Double P type Radiant Tube, - U TypeRadiant Tube, - W type Radiant Tube, The aim of the radiant tubes is to transfer heat to the load through irradiation.
