ASTM A179 / SAME SA179 Carbon Steel Seamless Tube Heat Exchange Tube
Description
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.
A179 tubes are used widely due to its excellent tensile strength and yield strength. The properties of the SA179 grade is highly unmatched, some of them are good corrosion resistance, oxidation resistance, pitting resistance, resistance to acid, crevice corrosion resistance and excellent strength.

Hardness requirements
The hardness coefficient of the steel pipe shall not exceed 72 HRB
Mechanical properties test requirements 1 Flattening test Take 2 steel pipes from each batch (Note 2) or use a fragment for testing.
Expansion test
Take 1 specimen from each of 2 steel pipes from each batch or use a fragment for testing.
If the bending test is used instead of the expansion test, when the wall thickness of the steel pipe is less than 10% of the outer diameter, take 1 specimen from each batch of steel pipes or use a fragment for bending test. Steel pipes that are not within the above specification range do not need to be bent.
Hardness test
Take 2 steel pipes from each batch for Rockwell hardness test. "One batch" should include all steel pipes with the same nominal diameter and wall thickness produced by the same heat treatment and the same batch of steel before cutting. When the final heat treatment is carried out in the same heat treatment furnace of the same model, "a batch" shall refer to all steel pipes of the same size heat treated in the same furnace. When the final heat treatment is carried out in a continuous heat treatment furnace, "a batch" shall include all steel pipes of the same size, heat, heat treatment at the same temperature, time and speed in the same furnace.
Hydrostatic test
All tube shall be subjected to hydrostatic test, or non-destructive electrical test pipes shall be used when the purchaser requires otherwise.
Application
Cold drawn tube
Condenser tubes
Heat exchanger tubes
Low carbon steel
Seamless tube
