ASTM A179 is a cold-drawn seamless low-carbon steel tube material specifically designed for heat exchangers. Its manufacturing and performance strictly comply with ASTM International standards to ensure reliability and cost-effectiveness under heat exchange operating conditions.
Material and Specifications
The core of this material is low-carbon steel, which is formed into seamless tubes through a cold-drawing process. This process significantly improves the dimensional accuracy and surface finish of the tubes. Its specifications are flexible, with outer diameters typically ranging from 1/8 inch (approximately 3.18 mm) to 2 inches (approximately 50.8 mm). The wall thickness is selected within the range permitted by the standard according to specific application requirements, balancing structural strength and heat exchange efficiency.
Chemical Composition
The chemical composition of ASTM A179 low-carbon steel must meet the requirements in the table below, with strict control over the contents of carbon, manganese, and other elements to ensure its workability and toughness.
Element
Content Range (%)
Carbon (C)
≤ 0.15
Manganese (Mn)
0.30 - 0.60
Phosphorus (P)
≤ 0.035
Sulfur (S)
≤ 0.035
Silicon (Si)
≤ 0.07
Copper (Cu)
≤ 0.08
Mechanical Properties
At room temperature, the mechanical properties of ASTM A179 steel tubes must meet the specifications in the table below, ensuring they can withstand a certain level of pressure and load during installation and service.
Mechanical Property
Requirement
Tensile Strength
≥ 310 MPa (45,000 psi)
Yield Strength
≥ 170 MPa (25,000 psi)
Elongation in 2 inches (50 mm)
≥ 30%
Applications
The primary application of ASTM A179 steel tubes is in heat exchangers, condensers, and evaporators and other heat exchange equipment. It is widely used in industries such as petrochemicals, electric power, refrigeration, and food processing for conveying various hot and cold fluid media. Its low-carbon composition and excellent weldability make it easy to connect with tube sheets, while the high precision and smooth inner surface achieved through the cold-drawing process help reduce fluid resistance, improve heat exchange efficiency, and ensure long-term stable operation under moderate pressure and temperature conditions.
