Tianjin Plate Heat Exchanger - How to Handle Leakage Issues of Fully Welded Plate Heat Exchangers
2020-07-24
The fully welded plate heat exchanger is a device that transfers part of the heat from the hot fluid to the cold fluid. The fully welded plate heat exchanger is a common device in many industrial sectors such as chemical, petroleum, power, food, and others, playing an important role in production. During the production process, due to the erosion of the tube sheet by water, cavitation, and the corrosion of trace chemical media, leaks often occur at the welds of the tube sheet, leading to the mixing of water and chemical materials, making it difficult to control the production process temperature, resulting in the generation of other products, severely affecting product quality and lowering product grade.

In the production process, due toFully welded plate heat exchangerthe tube sheet is subject to erosion from water, cavitation, and corrosion from trace chemical media, leaks often occur at the welds of the tube sheet, leading to the mixing of water and chemical materials, making it difficult to control the production process temperature, resulting in the generation of other products, severely affecting product quality and lowering product grade. After the condenser tube sheet weld leaks, traditional repair methods are usually used, which can easily create internal stress within the tube sheet that is difficult to eliminate, causing leaks in other heat exchangers. Moreover, the repair takes some time, and after a few months of use, the tube sheet welds corrode again, leading to waste of manpower, material resources, and financial resources.
To reduce the increase in costs, the corrosion resistance and erosion resistance of polymer composite materials can be utilized, and newFully welded plate heat exchangerprotection can be applied in advance, which not only effectively addresses theFully welded plate heat exchangerexisting weld and sand hole issues but also prevents chemical substances from corroding the metal surface and weld points of the heat exchanger after use. During future regular maintenance, polymer composite materials can also be applied to protect exposed metals. It is precisely due to this meticulous management thatFully welded plate heat exchangerthe probability of leakage issues is greatly reduced, not only lowering theFully welded plate heat exchangerequipment procurement costs but also ensuring product quality and production time, thereby enhancing product competitiveness.
