Hot story about heat exchanger components this week

There are many heat exchanger components and materials on the market now, so this week I will share with you a widely used classic heat exchanger component-finned tube.

Heat exchanger component-finned tube

Finned tube is a kind of heat exchange component, often used in high temperature and flue gas space. In our daily work, it can be seen everywhere, for example, the boiler needs to use finned tubes for heat exchange. For daily operations in such a harsh environment, the finned tube itself must have corrosion resistance and stability.

As a typical heat exchange component, in order to improve the heat exchange efficiency of the finned tube, fins are usually added on the surface of the heat exchange tube to increase the outer surface area of the heat exchange tube, thereby improving the heat exchange efficiency. In order to improve efficiency, heat exchange tubes are used.

As a finned tube manufacturer, Murphy has made great improvements to the corrosion resistance of the finned tube as heat exchanger component following long-term feedback from customers. In order to improve corrosion resistance, corrosion-resistant materials such as stainless steel and aluminum alloy are used in the manufacturing process of finned tubes. These materials have better corrosion resistance. Can effectively improve the service life of the heat exchanger and heat exchanger component.

Some customers report that the cost of these raw materials is generally high, and we have also taken corresponding countermeasures. Some corrosion inhibitors are used. The corrosion inhibitors have an effective protective effect on the metal surface of the fin tube. Substances can significantly reduce the corrosion rate of metal materials in the medium to zero. At the same time, the original physical and mechanical properties of metal materials can be kept unchanged.

Wear resistance is also a notable feature of finned tubes. If the finned tube suffers from abrasion, the heat exchange efficiency will be affected to a certain extent, so choose a finned tube with strong wear resistance. As a professional finned tube manufacturer, Murphy recommends that you consider using a kind of heat exchanger component-an integral finned tube, which has remarkable wear resistance. Because the integral fin tube fin and the base tube are integrally formed, the crystal structure is consistent, and the performance is stable.

Moreover, the fin is in the shape of a sand dune, which matches the shape of the temperature gradient when heated. Uniformity, no concentration, and no weak points of strength (and the main reason for wear is due to high temperature points, which should be low σ). In addition, the fins have a diversion effect on the flue gas. Make the various indicators of the flue gas (temperature, flow rate, ash content, etc.) more uniform, will not produce the flue gas flow, and will not cause the flue gas to scour a certain area or a certain part. Therefore, it is more wear-resistant.

Similarly, when choosing a finned tube, you need to pay attention to stability. Only when the stability is strong, the finned tube can be used in a high temperature environment without affecting the heat transfer performance.

In general, the finned tube has the functions of high heat exchange efficiency and large heat dissipation area. The whole heat exchanger component product has the advantages of long service life and wide temperature range. Users of Murphy finned tubes also come from various industries, such as petrochemicals, economizers, waste heat recovery, greenhouses, power station boilers, wood drying and so on. That’s it for the content of the finned tube shared this week. If you want to know more product information, please contact us.
