In the production process, due to the heat exchanger tube plate by water erosion, cavitation and micro chemical medium corrosion, tube plate weld often leakage, resulting in the mixing of water and chemical materials, production process temperature is difficult to control, resulting in the generation of other products, serious impact on product quality, reduce product grade. After the leakage of condenser tube plate weld, enterprises usually use the traditional repair welding method to repair, the internal stress of tube plate is easy to produce, and it is difficult to eliminate, resulting in leakage of other heat exchanger. Enterprises through pressure, inspection of equipment repair, repeated repair welding, experiment, 2~4 people need several days to complete the repair, after several months of use, the tube plate weld corrosion again, Bring to the enterprise manpower, material resources, financial waste, production costs increase.

Through the corrosion resistance and erosion resistance of Fushi blue polymer composite material, through the protection of the new heat exchanger in advance, it not only effectively control the weld and sand hole problems existing in the new heat exchanger, but also avoid the use of chemical corrosion heat exchanger metal surface and welding points, in the future regular maintenance, can also apply Fushi blue polymer composite material to protect the bare metal; Even if there is leakage after use, it can be repaired in time by Fushi Blue technology, so as to avoid the impact of long-term surfacing maintenance on production. It is because of this fine management that the probability of heat exchanger leakage problem is greatly reduced. It not only reduces the procurement cost of heat exchanger equipment, but also ensures product quality and production time, and improves the competitiveness of products.
