What is ASME SA 179 (ASTM A179) Standard Specification

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.

Referred standards for manufacturing SA 179 tubes

Related ASTM standards is ASTM A450/A 450M The standard specification for the general requirements for carbon steel, ferritic alloy, austenitic alloy steel tubes.
