1. Description:
ASTM A179 (SA179) 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 3.2mm to 76.2mm. 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 3.2mm, or thickness smaller than 0.015 inch and 0.4mm.
Manufacture: tubes shall be made by the seamless process and shall be cold drawn.
Heat Treatment: tubes shall be heat treated after the final cold draw pass at a temperature of 1200°F [650°C] or higher.
Inspection & Test: chemistry composition analysis, flattening test, flaring test, hardness test, NDT, surface inspection and dimension check.
Optional Test: flange test.
