Finned Metallic Tubes ASTM A214 Carbon Steel Extruded Aluminium Fin
Finned Metallic Tubes (ASTM A214 Carbon Steel Aluminium Fin) typically refer to steel-aluminum composite finned tubes. The base tube is made of carbon steel, while the fins are made of aluminum. Through specific processes (such as rolling and welding), the two are tightly bonded together to form a highly efficient heat exchange element.
- Tube Material:Carbon steel,Stainless steel,Tube Diameter:15.88-50.80 mm,Wall Thickness:1.0-3.0 mm
- Fin Material:Aluminum,Cooper,Fin Thickness:0.4-0.5 mm,Fin Pitch:2.1-6.0 mm,Fin Height:6.35-25.4 mm
Finned Metallic Tubes combine the strength of carbon steel with the excellent thermal conductivity of aluminum, and are widely used in chemical, petroleum, power, metallurgy, food drying, and many other fields.
Key Features and Applications of Finned Metallic Tubes
High Thermal Conductivity: Aluminum has excellent thermal conductivity, effectively increasing the heat exchange area and improving heat transfer efficiency.
Corrosion Resistance: The steel-aluminum composite structure exhibits good corrosion resistance in various environments, extending its service life.
Wide Applications: Particularly suitable for applications requiring high hygiene, such as food drying. Its smooth surface makes it easy to clean.
The ASTM A214 standard primarily specifies resistance-welded carbon steel tubes used in heat exchangers, condensers, and other equipment. “Carbon steel aluminum fins” typically refers to steel-aluminum bimetallic finned tubes, a high-efficiency heat exchange element that combines a carbon steel/stainless steel base tube with aluminum alloy fins through a composite process.
Finned Metallic Tubes Introduction
Base Tube Material: Common base tube materials include carbon steel (such as 20# steel, Q235B).
Fin Material: Fins are typically made of aluminum alloy.
Product Parameters: These finned tubes support a high degree of customization. Their “model” is usually defined by the following customizable parameters:
Base Tube Diameter: Typically ranges from 8-51 mm.
Base Tube Wall Thickness: Typically ranges from 1-5 mm.
Fin height: Typically ranges from 6-20 mm.
Fin spacing: Typically ranges from 2-8 mm.
Composite processes: Commonly include high-frequency welding and brazing.
The specific model of ASTM A214 carbon steel aluminum finned tube is not fixed, but defined based on the actual application requirements, using the combination of parameters such as the material and dimensions of the base tube and fins.
If you require a specific model, we recommend providing your specific operating conditions (such as operating temperature, pressure, and medium) directly to the supplier and contacting us to obtain the most suitable customized product solution.

Finned Metallic Tubes Appearance Dimension Inspection
Finned Metallic Tubes appearance dimension inspection is one of the important links to ensure the quality and performance of fin tubes.
The inspection items mainly include fin height, fin spacing, fin thickness, base tube wall thickness and outer diameter, etc.
Datang Extruded Finned Metallic Tubes Bending Processing
Bending of fin tubes is an important step in the production process of extruded finned metallic tubes. Bending is to bend the extruded finned metallic tubes material through specific mechanical equipment to form a suitable curvature to meet different usage requirements.
This step requires strict control of the bending angle and curvature to ensure the fit between the fin and the base tube and the heat dissipation effect.
Extruded Finned Metallic Tubes Pull Off Test
Extruded finned metallic tubes pull-off test is a test used to detect whether the fin tube will fall off when subjected to tension, mainly used to ensure the quality and reliability of the fin tube.
Datang’s this test is very important in the production process because the extruded finned metallic tubes will be subjected to various stresses during operation, such as temperature changes and pipe expansion, which may cause the fin to fall off, thereby affecting the performance and safety of the heat exchanger .
