ASTM A179 Seamless Carbon Steel Tube For Heat Exchanger And Condenser

ASTM A179 Seamless Carbon Steel Tube For Heat Exchanger and Condenser

ASTM A179 is a standard specification for seamless cold-drawn low-carbon steel tubes primarily intended for use in heat exchangers, condensers, and similar heat transfer equipment. These tubes are commonly used in industries such as chemical processing, power generation, oil and gas, and more due to their excellent thermal conductivity and durability.

Key Features:

1. Material: Low-carbon steel.
2. Seamless Construction: Manufactured via a cold-drawing process, ensuring a uniform structure and smooth surface finish.
3. Application: Designed for heat transfer in heat exchangers, condensers, boilers, and other equipment.
4. Good Thermal Conductivity: Low carbon content ensures excellent thermal performance and resistance to oxidation.

Chemical Composition:

Mechanical Properties:

Manufacturing Process:

1. Cold Drawing: Ensures dimensional accuracy, surface finish, and mechanical properties.
2. Heat Treatment: After the final cold-draw pass, the tubes undergo annealing to achieve the required microstructure and mechanical properties.
3. Testing: Tubes undergo hydrostatic testing, dimensional checks, and surface inspection to ensure quality.
