INDUCTION COILS

Liquid cooled coils provide a highly versatile tool for preheating, stress relieving, hydrogen bake out, and post weld heat treat in a variety of pipe diameters. Liquid cooled coils are great for preheat application on geometric that prevent use of air-cooled blankets. With liquid cooled coils, uniform heating is maintained along and through the heat zone by using induction to heat within the material. 

 Air-cooled coils may be the right choice when the maximum preheat temperature is 400°F. Air-cooled coils provide the same flexibility as liquid-cooled coils for preheating, and can be utilized in applications where the part is an irregular, non-standard shape that needs flexibility of wrapping the part.
