How to deal with the failure of heat exchanger

During the production process, due to the erosion of water, cavitation and corrosion of trace chemical media on the heat exchanger tube sheet, leakage often occurs at the weld seam of the tube sheet, resulting in mixing of water and chemical materials, making it difficult to control the temperature of the production process, resulting in Other products will seriously affect product quality and reduce product grades. After the condenser tube plate weld seam leaks, the company usually uses the traditional repair welding method to repair it. Internal stress is easily generated inside the tube plate and is difficult to eliminate, resulting in leakage in other heat exchangers. The company checks the repair of the equipment by suppressing it , Repeated repair welding and experiments, it takes 2 to 4 people a few days to complete the repair. After several months of use, the tube plate welds corrode again, which brings waste of manpower, material and financial resources to the enterprise, and increases the production cost. Through the corrosion resistance and erosion resistance of Fushilan polymer composite materials, through the protection of the new heat exchanger in advance, this not only effectively solves the problems of welds and sand holes in the new heat exchanger, but also avoids chemical substances after use Corrosion of the metal surface and welding points of the heat exchanger, in the future regular maintenance, you can also apply Fushilan polymer composite material to protect the exposed metal; even if there is leakage after use, it can be repaired in time through Fushilan technology, It avoids long-term surfacing repairs affecting production. It is precisely because of this kind of refined management that the probability of heat exchanger leakage is greatly reduced, which not only reduces the equipment procurement cost of the heat exchanger, but also ensures product quality and production time, and improves product competitiveness.
