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.

Testing Requirements for seamless ASTM Q179/SA179 carbon steel pipe
(1)Hydrostatic Testing:
Inspection test pressures produce a stress in the pipe wall equal
to 60% of specified minimum yield strength (SMYS) at room
temperature. Maximum pressures are not to exceed 2,500 psi for NPS
3 and under, and 2,800 psi for the larger sizes. Pressure is
maintained for no less than 5 seconds.
(2)Mechanical Tests:
Tensile Test: Either transverse or longitudinal are acceptable for
NPS 8 and larger
Tensile tests smaller than NPS 8: Longitudinal testing only
Flattening Test: NPS 2 and larger
Bending Test (cold): NPS 2 and under
