ASTM SA179M Cold Drawn Boiler Steel Tube Minimum Wall Thickness
Seamless cold drawn low carbon steel heat exchanger and condenser tubes ASTM A179/A179M, ASME SA179/SA179M
ASTM A179 covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat-exchange, 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.
