High-Efficiency G-Type Embedded Fin Tube (ASTM A179 Base + AL1060 Fin)

Product Overview As a leading manufacturer of heat transfer solutions, we proudly present our premium G-Type Embedded Fin Tubes, engineered specifically with an ASTM A179 seamless carbon steel base tube and AL1060 pure aluminum fins. Also known as grooved fin tubes, this product is designed for extreme thermal conditions where superior heat transfer and mechanical durability are mandatory. It is the ultimate choice for air coolers, heat exchangers, and rigorous industrial applications.

Structure & Manufacturing Process of ASTM A179 + AL1060 Embedded Fin Tube

The excellent performance of the G-Type finned tube lies in its unique mechanical bonding process.

• Base Tube (ASTM A179): We utilize high-quality cold-drawn seamless carbon steel (ASTM A179) which provides exceptional pressure resistance and long-term durability.

• Fin Material (AL1060): We select AL1060 Aluminum due to its outstanding thermal conductivity and excellent atmospheric corrosion resistance.

• The "G-Type" Embedding Process: A helical groove (approximately 0.3mm to 0.4mm deep) is plowed into the outer wall of the A179 base tube. The AL1060 aluminum fin strip is then continuously tension-wound into this groove. Finally, the displaced base metal is mechanically compressed back against the base of the fin, locking it permanently in place. This ensures a flawless metal-to-metal contact with zero thermal resistance.

Chemical Composition of ASTM A179 Base Tube & AL1060 Fin

To guarantee the highest quality, our raw materials strictly adhere to international standards. Below is the precise chemical breakdown of both materials:

Dimensions & Tolerances for A179 / AL1060 G-Type Fin Tubes

Precision is critical in heat exchanger manufacturing. Our state-of-the-art finning machines ensure that every A179 and AL1060 embedded fin tube meets highly restricted dimensional tolerances.

Performance Advantages of A179 Carbon Steel and AL1060 Aluminum Fin Tubes

• Unmatched High-Temperature Resistance: Unlike extruded or L-type fin tubes, the mechanical lock of the AL1060 fin into the A179 base tube allows for an operating temperature of up to 400°C (752°F) without the fin losing contact or peeling off.

• Superior Heat Transfer Efficiency: The "G" embedding process eliminates the air gap between the fin and the base tube, ensuring optimal heat conduction from the A179 steel to the AL1060 aluminum.

• High Vibration Resistance: The deep embedding of the fin ensures strong structural integrity, making it highly resistant to the intense vibrations commonly found in large industrial air cooler fans.

• Easy Cleaning: The robust connection allows for high-pressure water or steam cleaning without damaging or bending the fins.

Key Applications of ASTM A179 & AL1060 Embedded Finned Tubes

Due to their heavy-duty construction, our ASTM A179 and AL1060 G-Type Finned Tubes are the standard choice for severe industrial environments:

• Air Cooled Heat Exchangers (ACHE): Extensively used in forced draft and induced draft air coolers.

• Petrochemical & Oil Refineries: Ideal for cooling hot hydrocarbon fluids and condensing gases.

• Power Generation Plants: Used in steam condensers, boiler components, and exhaust gas coolers.

• Chemical Processing: Suitable for handling aggressive cooling environments where high temperature stability is required.
