ASTM A192 / ASME SA192 Carbon Steel Seamless Boiler Tube
Description
ASTM A192 and ASME SA179 are specifications that define the requirements for seamless carbon steel pipes used in boilers, superheaters, heat exchangers, condensers, and other pressure-containing applications.
These specifications cover carbon steel pipes. They are used in high-pressure, high-temperature environments such as boilers and heat exchangers. All are seamless, meaning they have no welds or joints, which makes them highly reliable under pressure.
The chemical composition of steel is critical to ensure the performance of the material under a variety of conditions. Typically, the composition includes:
Carbon (C): Typically less than 0.35%
Manganese (Mn): Up to about 1.60%
Silicon (Si): Up to about 0.70%
Sulfur (S): Limited to 0.035% or less
Phosphorus (P): Limited to 0.035% or less

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
