Double-P Type Radiant Tubes

Core Function: As the core heating element in sealed furnaces, the unique ‘Double P’ structure enables highly efficient and uniform heat radiation. It perfectly isolates combustion gases from the furnace atmosphere, ensuring process purity and workpiece quality while significantly improving the overall energy efficiency of the heating system.

Application Fields
Continuous Annealing Lines (CAL)
Hot-dip Galvanizing Lines (CGL)
Carburizing, Nitriding (Chemical Heat Treatment)
Powder Metallurgy Sintering Furnaces
