ASTM SA179 Seamless Embedded Fin Tube for Air Cooler
Astm sa179 seamless embedded fin tube for air cooler is a heat exchange element. Fins are added to the outer surface of the heat exchange tube to increase the outer surface area of the heat exchange tube and improve the heat exchange efficiency.
- Tube Material:SA179,Tube Diameter:15.88-50.80 mm,Wall Thickness:1.0-3.0 mm
- Fin Material:Aluminum,Fin Thickness:0.4-0.5 mm,Fin Pitch:2.1-6.0 mm,Fin Height:6.35-25.4 mm
ASTM SA179 Seamless Embedded Fin Tube for Air Cooler
The ASTM SA179 Seamless Embedded Fin Tube for Air Cooler uses a seamless cold-drawn low-carbon steel tube conforming to ASTM A179/SA179 standards as the base tube. Aluminum or copper fins are mechanically embedded into the outside of the tube to form a heat exchange element. Its core function is to increase the outer surface area of the heat exchange tube, thereby significantly improving the heat transfer efficiency of the air cooler.
The ASTM SA179 Seamless Embedded Fin Tube for Air Coolers has the following characteristics:
Material: The base tube is made of SA179 low-carbon steel (carbon content 0.06%-0.18%), and the fins are typically made of aluminum or copper.
Process: Utilizing mechanical embedding technology to ensure a tight bond between the fins and the base tube.
Performance: Tensile strength ≥325MPa, yield strength ≥180MPa, elongation ≥35%.
The ASTM SA179 Seamless Embedded Fin Tube is widely used in the manufacture of air coolers in industries such as power and chemical engineering. It is particularly suitable for applications with moderate operating temperatures, low media corrosivity, and cost sensitivity. Its installation must adhere to the principles of “precise positioning, reliable connection, and guaranteed sealing.”

ASTM SA179 Seamless Embedded Fin Tube for Air Cooler Appearance Dimension Inspection
Embedded fin tube 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 Embedded Fin Tube Bending Processing
Bending of fin tubes is an important step in the production process of G type fin tubes. Bending is to bend the embedded fin tube 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.
G Type Embedded Finned Tube Pull Off Test
G type embedded finned tube 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 g type finned 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 .
