Extruded fin tube Suppliers in China
The steel-aluminum composite extruded fin tube is rolled from an aluminum tube and a steel tube. The extruded finned tube adopts the form of a base tube sleeved with an aluminum tube. The aluminum tube is tightly sleeved on the base tube and is extruded by a machine to form fins. The base of the fin fits tightly with the outer wall of the tube. It is a wear-resistant, new and efficient hot-drying raw material. It will not break or melt at high temperatures.

Quality Control for extruded fin tube
The quality of the extruded fin 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.
Delivery condition:
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with Anti-rust at both ends of extruded fin tube.

Extruded Fin Tube By Industy
Steel-aluminum extruded fin tubes are widely used in various industrial fields such as refrigeration, air conditioning, petrochemical, and electric power. For example, in the refrigeration industry, finned tubes are often used as heat exchange elements for equipment such as evaporators and condensers; in the petrochemical industry, finned tubes are used for heat exchange in heating, cooling, condensation and other processes; in the electric power industry, finned tubes are used in heat exchange systems in equipment such as boilers, steam turbines, and generators.
Such as Air Cooler,Air preheater,Charge Air Chiller, Condenser,Evaporator, Fluid Cooler, Gas Cooler,Oil Cooler, Radiator, Refrigeration,Steam to Air Heat Exchanger etc.In addition,extruded fin tubes also play an important role in metallurgy,machinery,food and other industries.
Extruded Aluminum Fin Tube Advantages
Datang offers the widest variety of sizes available for extruded fin tube in the industry.
1. 100% fin-to-tube bond providing exceptional efficiency and longevity.
2. Excellent corrosion protection on the base tube.
3. Easy to clean with a high-pressure water jet without deforming the fins.
4. As the outer sleeve is continuous No galvanic corrosion between the tube and fins.
5. The bonding of the outer and inner tubes removes the risk of loss of contact with the aluminium due to thermal stress and fins are vibration resistant.
6. Higher heat transfer performance for the life of the unit.
7. Extruded Fin tubes are commonly used in applications with temperature up to 325 °c.

Differences Between Extruded Fin Tubes and Aluminum Wound Fin Tubes
The structure of extruded fin tubes is usually more compact, and the connection between the fins and the base tube is more solid, which makes it excellent in heat dissipation performance and has higher mechanical strength.
The structure of aluminum-wound fin tubes is looser, and the connection between the fins and the base tube is relatively weak, but this also makes it more flexible.
