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.
ASTM A179 (SA 179) standard specification covers seamless cold drawn low carbon steel pipe, for tubular heat exchanger, condensers and other similar heat transfer equipment.
The ASTM A179 tube covers the OD from 1/8” to 3”, which is 3.2m m to 76.2 mm. Other diameters and thickness smaller than the specified sizes also applicable to this standard, but mechanical properties is not applicable for the size smaller than 1/8” and 3.2 mm, or thickness smaller than 0.015 inch 0.4 mm.
Applications: For tubular heat exchangers,condensers,and similar heat transfer apparatuses.
Chemical composition contains carbon, manganese, phosphorus, and sulfur. Test required: hardness test, flattening test, flaring test, flange test, and hydrostatic test.
