In order to improve heat exchange efficiency, fins are usually added to the surface of heat exchange tubes to increase the outer surface area (or inner surface area) of heat exchange tubes, so as to achieve the purpose of improving heat exchange efficiency. Such heat exchange tubes are called fins. Sheet tube. What are the types of Finned Tubes ? Let's get to know it together.
Finned tubes are divided into square finned tubes, spiral finned tubes, longitudinally finned tubes, spiral serrated finned tubes, andComposite Laser Welded Finned Tubes,inner finned tubes according to shape and structure;
Finned Tubes are divided into: single metal finned tubes, bimetallic composite Finned Tubes according to the material;
Finned Tubes are classified according to different processing techniques: rolled finned tubes, welded finned tubes, rolled formed finned tubes, and suit formed Finned Tubes.
Laser welded composite finned tubes have a certain ability to prevent dust accumulation.Composite Laser Welded Finned TubesIn the concept of treating more, the use of finned tubes is a kind of fusion of mood, which effectively carries many different skills in use. It is also an effective way of using it.
The Finned Tube is a fin added to the surface of the heat exchange tube, and is a kind of heat exchange component. The heat exchanging components increase the fins, which also increases the surface area, thereby achieving better heat exchanging effect. In view of the fact that finned tubes are assembled on machinery and equipment similar to boilers, they must withstand the test of continuous high temperature, so when we select finned tubes, we must choose the following finned tubes with outstanding capabilities .
Finned tubes have low contact thermal resistance, and only by selecting finned tubes with low contact thermal resistance can the performance of finned tubes be guaranteed under continuous high temperature conditions.
Laser welded finned tubes are fins added to the surface of heat exchange tubes and are a type of heat exchange elements. The heat exchange element has increased fins, which increases the surface area, so that better heat exchange can be achieved. Since finned tubes are installed on equipment like boilers, they must stand the test of high temperature. Therefore, when purchasing finned tubes, you must choose the following finned tubes with outstanding capabilities.
First of all, the selected finned tubes should have Strong Corrosion Resistance
If the selected finned tube is not strong in corrosion resistance, it will be easily corroded in a high temperature environment
Second. The finned tube should have strong wear resistance
If the finned tubes are worn, the heat transfer efficiency will also be affected to a certain extent, so finned tubes with strong wear resistance should be selected.
Third. Finned tubes should choose low thermal contact resistance
Only by choosing finned tubes with low thermal contact resistance can the performance of finned tubes be guaranteed in high temperature environments
Fourth. Finned tubes should be selected with strong stability
Only by choosing a finned tube with strong stability can the heat transfer performance not be affected in a high temperature environment
Fifth. Finned tubes should have good anti-dust ability
Finned tubes are not easy to replace because they work in a high-temperature environment, so it may cause dust accumulation in the long run. Therefore, when purchasing finned tubes, choose finned tubes with good dust resistance.

What is Composite Laser Welded Finned Tube?
Finned Tubes are elongated flat Tubes made of aluminum clad carbon steel and fitted with brazed aluminum fins. These tubes are used in series for heat exchangers. The advantage they offer over normal tubes is the greater contact of the fins with the external liquid. This speeds up the heat exchange between the liquid inside the tube and the liquid outside the tube. With normal tubes, the rate of heat transfer will be much slower.
Finned Tubes come in different shapes.
What is the use of laser welded finned tubes?
Finned tubes are particularly useful in the case of air heat exchangers. In an air Heat Exchanger , heat transfer occurs between a liquid and a gas. Finned tubes can be very helpful due to the lower thermal coefficient on the air side. Finned tubes increase surface area, which facilitates faster heat transfer between components.
Advantages of using finned tubes
Finned tubes have the following advantages:
Improve heat transfer rate
The fins in the finned tube increase the contact surface area. This enables it to speed up the rate of heat transfer.
Improve heat transfer coefficient
In normal tubes, the outer surface area is about the same or slightly different than the inner surface area. In this case, the fluid with the lowest heat transfer coefficient will drive the overall heat transfer rate. Finned tubes increase the surface area significantly. This is particularly useful when the heat transfer coefficient of the fluid inside the tube is greater than the heat transfer coefficient of the fluid outside the tube.
Reduce equipment size and increase project cost efficiency
Finned Tubes can significantly increase the surface area. Using Finned Tubes can reduce the number of tubes used in an application. This leads to a significant reduction in the size of the device. In the long run, this can lead to lower project costs.
