ASTM A179 / ASME SA179 Carbon Steel Heat Exchanger Tube Seamless Steel Tubing
Key Features & Benefits of ASTM A179 / ASME SA179 Carbon Steel Heat Exchanger Tube
Excellent Formability: Low carbon content and annealing allow severe bending, expanding, and rolling into tube sheets.
Corrosion Resistance: Not stainless; but in clean, non-aggressive environments (water, steam, oil), it performs reliably. For aggressive media, protective coatings or cathodic protection may be used.
Weldability: Very good, though seam welding is not applicable (tubes are seamless). Suitable for joining by brazing or welding to fittings.
Cost Efficiency: Lower cost than stainless steel or high-alloy materials, while offering adequate strength for moderate temperatures and pressures.

Comparison with Similar Grades
| Grade | Standard | Key Difference |
|---|---|---|
| SA179 | ASME | Cold-drawn, mandatory heat treatment, fine grain, higher ductility. |
| SA192 | ASME | Higher carbon (0.06–0.18% C), higher tensile (≥55 ksi), for boilers. |
| SA210 A1 | ASME | Medium-carbon steel (C ≤0.27%), higher strength, for boiler tubes. |
| EN 10216-2 P195 | EN | Similar low-carbon seamless, slightly different mechanicals. |
| JIS G3461 STB340 | JIS | Japanese equivalent; comparable properties. |
SA179 vs. SA192:
SA179 requires cold-drawing and annealing, resulting in finer grain and better formability. SA192 may be hot-finished and is intended for higher-temperature boiler service.
Testing & Inspection (per ASME SA-450)
Hydrostatic Test: Each tube nondestructively tested (pressure or eddy current).
Nondestructive Electric Test: Eddy current or ultrasonic per SA-450, unless hydrostatic test is performed.
Flattening Test: To verify ductility.
Flange Test: For tubes intended to be rolled into tube sheets.
Hardness Test: Rockwell B.
Grain Size: Typically required to be ASTM No. 7 or finer.
Shell-and-Tube Heat Exchangers: Both shell-side and tube-side fluids, particularly for oil refineries, petrochemical plants, and power generation.
Condensers: Surface condensers in steam power plants.
Feedwater Heaters: Preheating boiler feedwater.
Air Coolers: Fin-fan coolers in process industries.
Hydraulic Systems: Low-pressure tubing in hydraulic lines.
Instrumentation: Sensing lines for pressure and temperature.
