ASTM A179 / ASME SA179 Carbon Steel Tube For Heat Exchanger And Boiler Application

Carbon Steel Tube ASTM A179 / ASME SA179 Heat Exchanger and Boiler Application

ASTM A179/ASME SA179 is a standard developed by the American Society for Testing and Materials (ASTM), which is a specific purpose seamless steel tube suitable for the thinnest seamless steel tube used in tubular heat exchangers, condensers, and similar heat conduction devices. The outer diameter specification of steel tubes specified in ASTM A179/ASME SA179 standard is between 1/8 inch and 3 inches (i.e. 3.2 to 76.2 millimeters), which is particularly suitable for thin-walled tubes.

The manufacturing process of seamless steel tubes includes hot rolling and cold drawing. ASTM A179 carbon steel tubes are typically manufactured using cold drawing technology. During the manufacturing process, steel tubes undergo heat treatment to improve their mechanical properties and corrosion resistance. After the final cold drawing, heat treatment shall be carried out at a temperature not lower than 650 ℃.

ASTM A179/ ASME SA179 Chemical Composition:

ASTM A179 carbon steel tube has a smooth surface without rust or oxide scale. Other surface qualities shall be in accordance with ASTM A450/A450M. Each batch of steel tubes needs to undergo strict testing, including hardness testing, flattening testing, expansion performance testing (or curling performance testing), and hydrostatic testing, to ensure that their quality and performance meet the requirements for use.

Application:

• Heat exchanger: ASTM A179 carbon steel tube has a small wall thickness and excellent heat transfer performance, making it an ideal material for manufacturing heat exchangers. Heat exchangers are used in various industrial processes to transfer heat, such as cooling, heating, and evaporation.
• Condenser: A condenser is another important heat transfer device used to condense steam or gas into liquid. ASTM A179 carbon steel tube has been widely used in the manufacturing of condensers due to its excellent corrosion resistance and thermal conductivity.
• Refrigeration system: In the refrigeration system, ASTM A179 carbon steel tubes are used to connect and transfer refrigerant, ensuring efficient operation of the system. Its excellent low-temperature performance makes it a key component in refrigeration systems.
• Chemical industry: In the chemical industry, ASTM A179 carbon steel tubes are used to treat various corrosive media such as acids, bases, and salts. Its excellent corrosion resistance ensures the safe operation and long-term stability of the equipment.
• Power industry: In the power industry, ASTM A179 carbon steel tubes are used to manufacture heat transfer components in boilers and power generation equipment, such as superheaters, reheaters, etc. Its high temperature strength and thermal conductivity make it an indispensable material in the power industry.
• Food processing industry: In the food processing industry, ASTM A179 carbon steel tubes are used for transporting and heating food media such as steam and hot water. Its hygiene and corrosion resistance ensure the safety and quality of food.
