What is ASTM A179?
ASTM A179/A179M is a standard specification for Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes. ASTM A179/A179M includes seamless cold-drawn mild steel tubes of minimum wall thickness for tubular heat exchangers, condensers, and similar heat transfer equipment.ASTM A179/A179M includes tubes with outside diameters from 1⁄8 to 3 inches [3.2 to 76.2 mm]. This specification covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. Tubes shall be made by the seamless process and shall be cold drawn. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, and sulfur. The steel materials shall also undergo hardness test, flattening test, flaring test, flange test, and hydrostatic test.
