ASTM A179 tube,A179M Seamless Cold-Drawn Tube,Low-Carbon Steel Heat-Exchanger and Condenser Tubes,ASTM A179 heat exchange tube
We offer Heat Exchanger Steel Tubing under specification ASTM / ASME / SA / A179.
ASTM A179/A179M is the standard specification for Seamless Cold-Drawn Low-Carbon Steel Heat Exchanger and Condenser Tubes.
ASTM A179 tubes for heat exchanger
ASTM A179 covers tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter.
ASTM A179 seamless steel tube
ASTM A179/A179M, ASME SA179/SA179M is the standard applicable to Seamless cold drawn low carbon steel heat exchanger and condenser tubes.
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.
ASTM A179: A179 is a low-carbon steel grade specifically designed for heat exchanger and condenser tubes. It offers excellent thermal conductivity and is suitable for both seamless and welded applications.
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.
