ASME SA192 / ASTM A192 Carbon Steel Seamless Tubes for Air Heater and Boiler 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.
