SA179 G Type Grooved-In Aluminum Fin Tubes for Heat Exchangers
SA179 G Type grooved-in aluminum fin tubes are specialized high-efficiency heat transfer components for heat exchanger applications. Their core features are as follows:
Ich. SA179 G Type Embedded Aluminum Fin Tubes Structural Design Features
- Grooved-In Process: Aluminum fins are mechanically embedded into spiral grooves on the surface of the carbon steel base tube, forming a metallurgical bond that significantly enhances interfacial heat transfer.
- Geometric Parameters:
- Base Tube: SA179 seamless carbon steel, standard OD 1 Zoll (25.4 Mm), wall thickness 0.109 Zoll (2.77 Mm).
- Flossen: Density 10 fins per inch (FPI) (~394 fins per meter), fin OD 2.25 inches (57.15 Mm), fin thickness 0.018 Zoll (0.46 Mm).
- Bimetal Composite: Combines carbon steel base tube (SA179) strength with high thermal conductivity aluminum fins (Al 1050/1060/3003, etc.).
II. SA179 G Type Embedded Aluminum Fin Tubes Core Performance Advantages
- Korrosion & Detachment Resistance: The grooved-in structure prevents fin loosening due to thermal cycling, suitable for high-vibration environments.
- High Heat Transfer Efficiency: Aluminum fins dramatically increase the heat dissipation area, significantly enhancing gas-liquid heat exchange efficiency, especially in air-cooler systems.
- Customization Flexibility: Supports extending base tube material to SA192, SA213 series alloy steels, or stainless steels to meet diverse operational requirements.
III. SA179 G Type Embedded Aluminum Fin Tubes Typical Applications
Primarily used in Air Fin Fan Coolers (AFFCs / Air Cooled Heat Exchangers – ACHEs) within the power generation and petrochemical industries, solving heat dissipation challenges for high-temperature fluids in space-constrained environments.
IV. SA179 G Type Embedded Aluminum Fin Tubes Compliance with Industry Standards
Strictly conforms to ASME SA179 material specifications, ensuring base tube reliability under high-pressure and high-temperature conditions.
