ASTM A179 ASME SA179 Finned Tube for Heat Exchanger
ASTM A179 ASME SA179 Finned Tube for Heat Exchanger
ASTM A179 Finned Tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of the ASTM A179 seamless heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency.
ASTM A179,ASME SA179 steel tubes covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.ASTM A179,ASME SA179 covers tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter.

Manufacturing Process of ASTM A179 Finned Tube
Fin strips (usually aluminum and copper) are folded into an L shape and wound under tension on the surface of the base tube. The feet of the fins are connected together and cover the surface of the fins.
ASTM A179 Finned Tube is combined with two different materials
Core tube material: A179
Fin material: aluminum, copper, steel
1. Aluminum (Alu.1100, Alu.1060)
2. Copper.
3. Steel
