ASTM A179 ASME SA179 Finned Tube for Heat Exchanger
We are the professional manufacturer and supplier of ASTM A179 ASME SA179 Finned Tube for Heat Exchanger
ASTM A179/A179M is the standard specification for Seamless Cold-Drawn Low-Carbon Steel Heat Exchanger and Condenser Tubes.
Finned tubes, also known as finned pipe or finned tubing, are heat exchanger components designed to enhance 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.
SA179 Finned Tubes are heat exchanger components made from SA179 carbon steel tubes with fins attached to the outer surface
SA179 based tube
ASTM A179 tubes Size range：1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter.
Tube Fins can be of different types, such as plain, serrated, or spiral, and are typically made from materials like aluminum or copper.
ASTM A179 or ASME SA179 cold drawn seamless carbon steel tube is applicable to tubular heat exchanger, condenser different similar heat transfer equipment with the minimum wall thickness.
This type of cold drawn seamless steel tube is widely used in chemical engineering, carbon treatment, oil refining, nuclear electric power generation, aviation, and so forth. STM A179 or ASME SA179 seamless carbon steel pipe is also used for manufacturing boiler water cold wall, economizer, reheater and steam cylinder.
