Specification

Standard

ASME SA-179/SA-179M is a globally recognized standard governing cold-drawn seamless low-carbon steel tubes for heat exchangers, condensers, and heat transfer systems. It covers both imperial (SA-179) and metric (SA-179M) units, ensuring uniformity in material properties, manufacturing, and dimensional accuracy. Compliance guarantees adherence to strict quality benchmarks, facilitating international acceptance.

Dimensional Specification:

Precise ranges are defined: outer diameters (OD) from 6.35mm to 152.4mm (0.25in to 6.0in) and wall thicknesses (WT) from 0.71mm to 12.7mm (0.028in to 0.500in).

Tight tolerances ensure compatibility with flanges, gaskets, and tube sheets. Lengths are customizable

 (e.g., 6m/20ft fixed lengths or random lengths), offering flexibility for diverse installations.

Mechanical Stability: High tensile/yield strength resists deformation under operational pressures/temperatures.

Ductility: Excellent elongation allows bending, flanging, and fabrication without failure.

Heat Transfer Efficiency: Seamless design and smooth surface eliminate thermal barriers, ensuring uniform heat conduction.
Formability: Easy integration into complex assemblies via standard welding/bending techniques.

Chemical Element Analysis

Controlled low-carbon composition:

Carbon (≤0.15%) enhances weldability; Manganese (0.30–0.60%) boosts strength; Phosphorus/Sulfur (≤0.035% each) prevent brittleness;

Silicon (≤0.30%) improves formability.

This composition balances strength and ductility for heat transfer applications.

Test Data Highlight

Tensile strength: 310–450 MPa (45,000–65,000 psi).
Elongation: 30–40% (thin walls); 25–35% (thick walls).
Hydrostatic test: Minimum 5 MPa (725 psi) for 10 seconds without leakage.
Surface roughness: ≤1.6 μm (Ra), ensuring efficient heat transfer.

Application Scenarios

Widely used in power generation (steam condensers),

chemical processing (process fluid heat exchangers),

oil/gas (refinery heat transfer equipment), HVAC (chillers),

food/beverage processing (cleanable systems), and marine (shipboard condensers).

Ideal for low to moderate pressure/temperature heat transfer.
