Bi Metallic Extruded Serrated Finned Tube - China

Extruded Serrated Finned Tubes is similar to extruded aluminum fin tube, but the aluminum fin is serrated, which greatly improve the fin tube heat transfer capacity.

The extruded finned tubes are produced by compressing an aluminum tube.

The aluminum fin is formed from bi-metallic tubes, a base tube, and an aluminum muff tube.

The fins are formed on a cold rolling process from the wall thickness of the aluminum muff tube.

Extruded fin gives very good corrosion protection to the base tube, as the base tube is not visible to the atmosphere in between the fins.

The maximum operating temperature for the extruded finned tube is 300°C.

As a result, the tube's base is completely connected to the main tube.

Since these fins never break, deform, or loosen, their heating efficiency does not change over time.

Advantages: - Corrosion resistance in the air is very high - Easy cleaning

- Excellent efficiency

- More reliable capacity for thermal transfer.

Fin material is aluminum (standard form) and copper (occasionally).

The tube material can be copper, copper-nickel, titanium, carbon steel, or stainless steel.

The extruded finned tubes are produced by compressing an aluminum tube, or sleeve, onto the base tube.

The bloom is exposed to very high pressures which essentially "grows" the fins into the final fin profiles.

This process manufactures an excellent strong joint with great resistance (fin stiffness) as well as exceptional heat transfer capabilities (longevity, temperature range).

The advantage of extruded fin tubes are full protection of bare tube against corrosion and the fin has high mechanical strength.

Extruded finned tubes provide the most stable performance over time as compared to the other fin types.

The fin is rolled from an outer aluminum tube by a process using pressure to create a rolled "pressure bond" between the liner tube and fins.

The aluminum fin material completely encloses the tube, except at the ends where a tube coating can be applied.

Application:

- Primarily extruded finned tubes are used in high-temperature conditions and corrosive atmospheric conditions, such as operating temperatures less than 300°C or off-shore applications; - Heat pipes air to air heat exchangers for HVAC applications, air dehumidification in air treatment plants, and energy recovery in the air exhaust system.

- This kind of fin design is the least economical as compared to the other fin types; the main reason is due to the increased amount of aluminum used around 40% also the increased labor during the manufacturing.

However, this increased cost can be compensated if using lower-grade parent tube material.
