ASTM A179 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.
