ASTM SA-179 Seamless Finned Tubes For Air Cooled Condenser
ASTM SA-179 seamless finned tubes (Groovy Fin Embedded With Aluminum Fins) are high-performance components specifically designed for air-cooled condensers, heat exchangers, and boiler systems; their key advantages lie in superior thermal conductivity and corrosion resistance.
Manufactured in accordance with the ASTM A179/A179M standard using a cold-drawn, low-carbon steel process, these tubes are particularly well-suited for heat exchange equipment in the power generation, petrochemical, and chemical industries.

In industrial heat exchange equipment procurement, the quality of embedded finned tubes directly determines the operational efficiency and service life of the equipment. Every single tube produced by Datang Finned Tube is fully traceable by our Quality Control Department and guaranteed to be leak-free. We fully provide ISO certifications and Material Test Certificates (MTC / Mill Test Certificates) for all products.
ASTM A179 Base Pipe Fin Aluminum
ASTM SA-179 seamless steel tubes for air-cooled condensers are engineered for high-efficiency heat transfer, with strict dimensional tolerance and excellent corrosion resistance, ensuring long-term stable operation under high-temperature and high-pressure working conditions.
High-performance aluminum fins are precision-rolled from high-purity aluminum foil as thin as 0.03mm,They effectively expand the heat exchange area by over 18%, reduce air resistance by 12%, and boost the overall cooling efficiency of your equipment while cutting long-term energy consumption.
Air cooler tube sheets, precision CNC machined from premium carbon steel, stainless steel or alloy steel, are perfectly tailored for ASTM SA-179 finned tubes. With accurate hole positioning and tight flatness control, they deliver leak-proof sealing under long-term high-pressure, high-temperature air cooling operations.
Fin tube support collar suitable for aluminum finned tube, extruded finned tube and L/ll / KL finned tube, and ismost commonly used in G-type finned tube.Our fin tube supports secure air cooler finned tube bundles firmly, preventing sagging, vibration and abrasion.
G-type Embedded Fin Tube Production Line
This G-type embedded fin tube production line is a fully automated precision manufacturing system dedicated to grooving the base tube, embedding aluminum fins and rolling the fin root tightly in one continuous workflow. It ensures zero fin loosening even under frequent thermal shocks, delivering consistent high-quality G-type fin tubes with stable heat transfer performance for air cooler applications.

ASTM SA-179 Seamless Finned Tubes Application
The basic heat transfer element of the embedded fin tube for heat exchanger is the embedded finned tube. By adding fins outside the tube, the heat transfer area is greatly increased.
The main advantages of G type finned tube-embedded fin air cooled heat exchanger include high efficiency, corrosion resistance, low noise, energy saving and environmental protection.
Embedded fin tube economizer can effectively recover waste heat in flue gas, reduce exhaust gas temperature, improve boiler efficiency, reduce energy waste and reduce operating costs.
