ASTM A179/A179M, ASME SA179/SA179M is the standard applicable to Seamless cold drawn low carbon steel heat exchanger and condenser tubes.
ASTM A 179 covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular, heat exchanger, condensers, and other heat transfer services. seamless ASTM A 179 steel pipe is supplied and produced by cold drawning.
Chemical composition contains carbon, manganese, phosphorus, and sulfur. Test required: hardness test, flattening test, flaring test, flange test, and hydrostatic test.
