Product Description
SA 179 Tubes/ASTM A179 Tubing for Heat Exchanger

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. In most cases, ASTM A179 replaces ASTM A178 in China.

  • 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.
  • Delivery Condition: pickling, nitrogen protection surface or bright annealing. Some south korea mills buy mother tubes and only do bright annealing heat treatment in their country, because pickling is a must, but many countries don't allow this process. And nitrogen protection is now popular in China, the surface is similar bright apperance, but low cost.
  • Inspection & Test: chemistry composition analysis, tensile test, flattening test, flaring test, hardness test, NDT, surface inspection and dimension check.
  • Optional Test: flange test.

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
