ASTM A179 - Seamless Steel Pipe
Detailed introduction:
Use: used in coolers, heat exchangers and other systems.
Steel type: low carbon steel.
Standard content: This standard applies to seamless cold-drawn steel pipes used in cooling, heat exchangers and air conditioning systems. The inner and outer surfaces of the pipe are smooth and suitable for heat exchange processes.
Main uses:
Heat exchangers, condensers, boilers and hot water systems.
Chemical equipment, cooling systems.
HVAC (heating, ventilation and air conditioning) systems.
ASTM A179 is used for boiler and heat exchanger pipes, divided into A, B, and C grades. The size ranges from OD 1.25 inches to 8 inches (≈32–203mm), and the wall thickness is generally Schedule 40 and 80. The chemical composition is similar to A106: C≤0.30%, Mn≤1.35%, Si≤0.10%, P, S≤0.045%. Physical properties: density 7.85g/cm³, Young's modulus 200GPa, thermal expansion coefficient 12×10⁻⁶/°C. Mechanical properties Tensile strength ≥415MPa, yield strength ≥205MPa, and there are certain requirements for low-temperature impact performance.
