Anti-corrosion of finned tube heat exchanger

2023-01-14

During the use of Finned Tube heat exchangers, it is very important to prevent corrosion phenomena. In order to prevent this phenomenon from happening, some corrosion-resistant materials, such as some Stainless steel and aluminum alloys, are used in the production process, and their corrosion resistance is relatively strong.

Effectively improve the life of the Heat Exchanger. However, the cost of such materials is generally relatively high, so the purchase price is relatively high. Use some corrosion inhibitors, in corrosive media, add some small amount of substances to greatly reduce the corrosion performance of the metal, and then stop, it is also some corrosion inhibitors we use.

Fin Tube

Electrochemical protection is used to protect the cathode and anode, the protection of the cathode DC power supply and the protection of the anode on the metal surface. The power consumption used in this way is very large, and the cost of use is naturally high. It is protected by anode protection method of anode protection of the equipment external power supply.

The basic function of the Finned Tube Heat Exchanger is to transfer heat and transfer part of the heat of the hot fluid to the cold fluid. Therefore, improving the use capacity of the heat exchanger is to improve its heat transfer performance, so as to realize the heat exchanger. transfer heat. Under the premise of comprehensive consideration of fluid resistance and no fluid-induced vibration, the flow rate should be as high as possible.

For fluids without phase change, the heat transfer method should be as close as possible to countercurrent flow. The purpose of this is to increase the average temperature difference and reduce heat transfer in the structure.
