Plate heat exchanger troubleshooting
In the production process, because the tube plate of the plate heat exchanger is subjected to water erosion, cavitation and trace chemical medium corrosion, the tube plate weld often leaks, resulting in mixing of water and chemical materials, and the production process temperature is difficult to control. Lead to the production of other products, seriously affecting product quality.
After the weld of the tube sheet of the condenser leaks, internal stress is easily generated inside the tube sheet, causing leakage of other heat exchangers. Repeated repair welding and experiment, 2 to 4 people need several days to repair, after using for several months Corrosion of the tube sheet welds again, bringing waste of manpower, material resources and financial resources to the enterprise, and increasing production costs. Through the corrosion resistance and erosion resistance of polymer composites, by protecting the new heat exchanger in advance, this not only effectively controls the weld seam and blisters in the new spiral plate heat exchanger, but also does not use post-chemical corrosion. The heat exchanger metal surface and solder joints can also be coated with polymer composite materials to protect the metal during regular maintenance. Even if leakage occurs after use, it can be repaired in time to avoid long-term surfacing maintenance. produce.
