Enamel Tube is the innovative evolution of the vitreous connecting flue pipe using modern engineering design principles, combined with «state of the art» manufacturing process. This provides the optimum solution for connecting flue pipes.
Enamel Premium range is seam-welded with a high quality enamel coating, with a minimum of two coats.
1. The enameled tubes are not easily broken enamel surface, no crack, acid and alkali resistance, resistance to gas erosion, smooth and high, gas flow resistance, easy Fouling;
2. As the flue gas across tube, the flue gas side of the heat capacity of exile to strengthen, under the same heat transfer coefficient (enamel thickness ratio of thermal conductivity with very small, about 0.0002, the calculation is negligible), wall temperature vertical preheater than ordinary steel increased 10-30 Degree Celsius, the overall heat transfer coefficient of about 20.3-24.2W;
3. two horizontal enamel sealing tube box, the sealed tube box structure welded high strength, pipe damaged or the overall change can only block, and heat-packing seal, can only replace the damaged pipe tube, easy maintenance;
4. The preheater is mainly used for boiler preheater, the low temperature.
