Aluminum Finned Tube for Heat Exchanger
Datang is your specialist in the field of aluminum finned tubes. These finned tubes have various applications and are used in heat exchangers, for example. Use the finned tube when the heat transfer coefficient on the outside of a tube is less than the same coefficient on the inside of it. The fins of a finned tube stimulate heat transfer, which enhances the effect of the heat exchanger.
Quality Control for Aluminum Finned Tube
The quality of the Aluminium finned tube is assured by hydrostatic or pneumatic testing, eddy current testing and tensile testing to verify the mechanical bond between the inner tube and the outer fins.
Datang Fin Tubes Delivery condition:
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with Anti-rust at both ends of copper finned tube.
Application fields of aluminum fin tubes:
Aluminum finned tube is widely used in water-cooled air heat exchangers and high-temperature water radiators in the petroleum and chemical industries.
Aluminum Fin Tube Classification
Aluminum finned tubes are offered in different variants. It is mainly important to look at the thermodynamic properties that the outside of a tube has. This determines to what extent additional surface is needed. You can also choose from a high or low finned on the aluminum finned tubes. A low finned tube is often chosen for oil-based coolers. Whereas in systems with air on the outside, a high finned tube is more likely to be chosen. A third factor is the choice between an L-fin, a G-fin, an E-fin and an I-fin.
Aluminium Extruded Fin Tube
Aluminium extruded fin tube is a single-metal composite finned tube rolled from an aluminum tube, with no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and a considerable extended heat exchange surface.
Aluminium G Type Embedded Fin Tube
Aluminium G type embedded finned tube is that the fin strip is tension wound and placed in the groove cut into the tube with appr, 0.4mm groove depth, then the bottom of the fin is guided into the groove and backfilled with base tube Firmly, finally lock the fins in place by rolling the grooves enclosed in the bottom of the fins. The maximum operating temperature of G Type Embedded Finned Tube can reach 400°C.
Aluminium LL finned tube
Aluminium LL finned tube is a finned tube in which the fin feet are preformed into an LL shape (overlapping LLs) and a strip of aluminum fins is applied to the base tube under tension. However, the feet are pre-formed so that one foot overlaps the other, increasing the base tube protection and thermal contact area of the finned tube. LL Type Finned Tube is usually used in steam coils, air pre-heaters., the maximum operating temperature can reach 180 °C.
Aluminium KL type finned tube
Aluminium KL type finned tube is a kind of knurled finned tube. Before winding the fins, knurl patterns on the base tube, or add a blade to the winder, knurl on the base tube, and use the back blade A finned tube made by winding, knurling and winding at the same time.
The KL Type Finned Tube relies on maximum surface contact between the fins and the tube, which is ensured by the tension of the fin strips helically forming around the pre-knurled tube, providing improved bonding and heat transfer. The maximum working temperature of KL Type Finned Tube can reach 250°C, and the maximum working pressure can reach 3.2MPa.
Aluminium L Type Finned Tube
Aluminium L Type Finned Tube is a finned tube made of aluminum fin tape folded into an L-shaped spiral under tension and wrapped tightly around the outer surface of the base tube.
The tension in the fin strips of the L Type Finned Tube wraps around the tube, causing the fin feet to press forcefully against the tube, holding the fins firmly in place. L Type Finned Tube is usually used in air coolers in petrochemical, power, paper, tobacco, building heating and other industries as well as heat exchangers in power plants (electricity, nuclear, thermal and geothermal power plants), the maximum operating temperature can reach 230°C.
Advantages of Aluminum Fin Tubes
1. Aluminum finned tubes have the characteristics of efficient heat transfer. The thermal efficiency of boilers using aluminum finned tubes can be increased by 5% to 10%, which means huge energy savings for large industrial boilers.
2. The design of aluminum finned tubes makes them lighter, which not only reduces energy consumption during transportation and installation, but also reduces costs.
3. Aluminum finned tubes have good corrosion resistance, can cope with wet and dry working conditions, are not easy to rust, and have good corrosion resistance. This characteristic enables aluminum finned tubes to maintain stable and efficient operation in various environments.
