What Materials are Commonly Used in Finned Tubes?

Finned tubes are widely used in various industries for enhanced heat transfer. The most commonly used materials for finned tubes include steel, copper-aluminum composites, copper, and aluminum. However, cast iron finned tubes are no longer prevalent in the market.

1. Steel Finned Tubes:

Steel finned tubes offer advantages such as light weight, high pressure resistance, low production energy consumption, and an appealing appearance. They are available in a wide range of styles and colors and can be fully water maintained, which extends their service life. However, it is important to note that steel finned tubes are prone to oxidation and corrosion in the presence of oxygen. Open boilers and water systems have strict requirements for oxygen content. Therefore, proper water maintenance should be carried out during the heating period. Inadequate maintenance may lead to severe corrosion and eventually result in water leakage from the finned tubes. Consumers using open heating systems should carefully consider the suitability of steel finned tubes.

2. Copper Finned Tubes:

Copper finned tubes are a popular choice for many consumers due to their corrosion resistance and long service life. Copper has excellent thermal conductivity, ensuring fast heat dissipation and high efficiency. Additionally, copper finned tubes enable convenient room temperature regulation. They have a compact shape, occupying minimal space while delivering high efficiency and energy savings.

3. Aluminum Finned Tubes:

Aluminum finned tubes are characterized by their small size, fast heat dissipation efficiency, and good anti-oxidation and corrosion performance. However, they are susceptible to corrosion by alkali. Proper internal corrosion protection measures are necessary. Currently, the use of aluminum finned tubes is less prevalent among users.

4. Copper-Aluminum Composite Finned Tubes:

Copper-aluminum composite finned tubes offer the advantage of separately treating the ventilation component and heat dissipation component within the fin tube. The copper material provides long-term corrosion resistance, while aluminum offers lightweight properties, good heat conduction, and ease of forming. Copper is used as the water-passing component, ensuring strong corrosion resistance and a longer service life compared to ordinary steel pipes used in heating systems. By using copper as the water-passing component, the copper-aluminum composite finned tubes achieve higher pressure-bearing capacity, enhancing their work pressure capabilities. The aluminum heat dissipating component has a low density, is easily formed, lightweight, and corrosion-resistant. However, the style options for copper-aluminum composite finned tubes are relatively limited, mostly available in white, and they are prone to deformation during long-distance transportation.

When selecting finned tubes, caution should be exercised. Different materials should be chosen based on specific requirements, considering the quality and performance of the finned tubes. Currently, steel finned tubes and copper-aluminum composite finned tubes are widely favored due to their effectiveness and ability to enhance the aesthetics of the home environment, gaining popularity among users in the market.
