Treatment of Common Problems of Heat Exchanger

2021-11-09

In the production process, due to water erosion, cavitation and corrosion of trace chemical media in the heat exchanger tube sheet, leakage often occurs at the weld of the tube sheet, resulting in mixing of water and chemical materials, and the production process temperature is difficult to control, resulting in the generation of other products, seriously affecting product quality and reducing product grade. After the

condenser tube plate weld leakage, the enterprise usually uses the traditional repair welding method to repair, the tube plate is easy to produce internal stress, and it is difficult to eliminate, resulting in leakage of other heat exchangers, the enterprise through pressure, inspection equipment repair, repeated repair welding, experiments, 2~4 people need several days to repair, after a few months of use tube plate weld corrosion again, to the enterprise to bring human, material and financial resources waste, increased production costs.
