How to deal with the leakage of semi-welded plate heat exchanger

Author:


During the production process, due to water erosion, 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 sheet weld leaks, it is usually repaired by traditional repair welding methods. Internal stress is easily generated inside the tube sheet, and it is difficult to eliminate, resulting in leakage in other heat exchangers. It will take a period of time to complete the repair, and After several months of repair, the tube-sheet welds corroded again, which caused a waste of manpower, material and financial resources.

In order to reduce the increase in cost, 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 the corrosion of the metal surface and welding points of the heat exchanger by chemical substances after use. During regular maintenance in the future, polymer composite materials can also be applied to protect the exposed metal; even if leakage occurs after use, it can be repaired in time to avoid long-term surfacing maintenance that affects 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.
