ASME SA192 / ASTM A192 Carbon Steel Seamless Tubes for Air Heater
Application
ASTM A192 carbon steel tube is a high-pressure seamless carbon steel boiler
tube produced according to the standard specifications established
by the American Society for Testing and Materials (ASTM). ASTM A192
carbon steel tubes must be manufactured using seamless processes
and undergo appropriate heat treatment to ensure their performance
meets standard requirements. Hot processed steel tubes do not
require heat treatment, while cold processed steel tubes require
heat treatment at 1200 ° F (650 ° C) or higher after final cold
processing.
ASTM A192 carbon steel tubes has strict requirements of the chemical
composition to ensure their strength, toughness, and corrosion
resistance. The carbon (C) content is between 0.06% and 0.18%, and
low carbon content helps to improve the toughness and welding
performance of the steel tube; The content of silicon (Si) should
not exceed 0.25%. Silicon mainly plays a role in deoxidation in
steel, which can improve the strength and hardness of steel;
Manganese (Mn) content ranges from 0.27% to 0.63%. Manganese can
enhance the strength and hardness of steel, refine grain size, and
improve the wear resistance and fatigue resistance of steel tubes;
The maximum content of phosphorus (P) is limited to below 0.035%;
The maximum content of sulfur (S) is limited to below 0.035%.
Strictly controlling the content of phosphorus and sulfur
impurities can effectively avoid defects such as brittle fracture
in steel tubes caused by excessive impurities.

Application:
- High pressure boiler components: ASTM A192 carbon steel tubes are commonly used for key components
such as heating surface tubes, headers, and economizers in
high-pressure boilers. These components need to withstand high
temperature and high pressure steam or hot water, so steel tubes
are required to have excellent resistance to high temperature and
high pressure.
- Superheater and reheater: ASTM A192 carbon steel tubes are used to transport
high-temperature and high-pressure steam in the superheater and
reheater, ensuring effective circulation and energy conversion of
steam in the boiler system.
- Petrochemical industry: ASTM A192 carbon steel tubes also play an important role in the
petrochemical industry. They are used in high-temperature and
high-pressure fluid transmission systems, such as steam pipelines,
heaters, etc., to ensure the smooth progress of the production
process.
- Power industry: ASTM A192 carbon steel pipes are widely used in the manufacturing
of power plant boilers. As the main structural components of
boilers, they bear high temperature and high pressure steam
pressure, ensuring the safe and stable operation of power plant
boilers.
