Product Description

Centrifugal Casting Radiant Heat Tubes 
for Steel Mills heat treating furnaces CAL & CGL

Product Description

There are few different shapes of Radiant Tubes, but  "W" and "U" tube systems are the most common types used in currently installed industrial furnaes.
Usually there is burner inside, so the radiant tubes is to transfer heat to the load through irradiation.

The Better Quality Radiant Tubes offer a consistent heat transfer, longer life, improve production, save energy, and reduced maintenance.
