ASME SA179 Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger Tube(Minimum-Wall-Thickness)
ASME SA179 is a standard specification for seamless cold-drawn low-carbon steel tubes specifically manufactured for use in heat exchangers, condensers, and similar heat transfer apparatus. These tubes are produced through a cold-drawing process to achieve precise dimensional tolerances, a smooth surface finish, and uniform mechanical properties. The low-carbon steel composition ensures excellent ductility, good thermal conductivity, and ease of fabrication, such as bending and expanding. ASME SA179 tubes are widely used in industrial applications requiring reliable performance under moderate temperature and pressure conditions, and they must comply with the mechanical and chemical requirements outlined in the ASME Boiler and Pressure Vessel Code, Section II.
