How to repair the leakage of the air heat exchanger?

Any product has a warranty period, but there may be product damage during the warranty period. If there is product damage during the warranty period, how can we deal with it? Here are the air heat exchanger manufacturers to introduce how the heat exchanger leaks:


An air heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Air heat exchangers are common equipment in the chemical, petroleum, power, food and many other industrial sectors and occupy an important position in production. There are many types of heat exchangers, but the principles and methods of heat exchange between cold and hot fluids can be basically divided into three categories: partition type, hybrid type and regenerative type.


In the production process, due to water erosion, cavitation and trace chemical media corrosion, the tube plate welds often leak, resulting in mixing of water and chemical materials, and the production process temperature is difficult to control, resulting in Generate other products, seriously affect product quality and reduce product grade. After the weld of the tube sheet of the condenser is leaked, it is usually repaired by the traditional repair welding method. The internal stress of the tube sheet is easy to be generated, and it is difficult to eliminate, causing leakage of other heat exchangers, and the repairing time takes a while, and After repairing, the corrosion of the tube sheet welds is repeated for several months, causing waste of manpower, material resources and financial resources.


In order to reduce the cost increase, the corrosion resistance and the anti-scourability of the Fushui blue polymer composite material can be protected by the protection of the new heat exchanger in advance, so that the weld seam and the sand hole problem existing in the new heat exchanger can be effectively controlled. It also avoids the use of chemical substances to corrode the metal surface and solder joints of the heat exchanger. In the future regular maintenance, Fushun blue polymer composite material can also be applied to protect the exposed metal; even if leakage occurs after use, Timely repair by Fusitlan technology avoids long-term surfacing maintenance affecting production. It is precisely because of this refined management that the probability of leakage of the heat exchanger is greatly reduced, which not only reduces the equipment procurement cost of the heat exchanger, but also ensures the product quality, production time and product
