ASME SA179 Carbon Steel G Finned Tube, Embedded Fin Tube For Air Cooler
1. Material Specification (ASME SA179):
Compliance: ASME SA179 specifies seamless cold-drawn low-carbon steel tubes, ideal for heat exchangers, condensers, and air coolers.
Properties: Excellent thermal conductivity, moderate strength, and cost-effectiveness. Suitable for high-pressure applications due to seamless construction.
Limitations: Limited corrosion resistance; may require coatings or maintenance in harsh environments.
2. Embedded Fin Tube Design:
Construction: Fins are integrally formed from the base tube via extrusion or rolling, ensuring direct metallurgical bonding. This contrasts with welded or wrapped fins.
G Finned Design: The "G" designation may refer to a specific fin geometry (e.g., gauge, height, or series) optimized for enhanced surface area and airflow.
| Element | Composition (Max %) |
|---|---|
| Carbon (C) | 0.06–0.18 |
| Manganese (Mn) | 0.27–0.63 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Property | Requirement (ASME SA179) |
| Tensile Strength | ≥ 325 MPa (47,000 psi) |
| Yield Strength | ≥ 180 MPa (26,000 psi) |
| Elongation | ≥ 35% |
| Hardness | ≤ 72 HRB (Rockwell B) |
Cost-Effective: Low-carbon steel balances performance and affordability.
Durability: Embedded fins resist mechanical wear and thermal fatigue.
Customization: Fin geometry and tube dimensions tailored to specific cooling loads.
HVAC&R Condensers (Commercial/Industrial Systems)
Function: Reject heat from refrigerants (e.g., ammonia, Freon) to air or water.
Use Case:
Evaporative Condensers: SA179 tubes transfer heat to water/air mixtures.
Air-Cooled Chillers: Finned tubes enhance heat rejection in outdoor units.
Advantages:
Lightweight and easy to install in compact HVAC systems.
Suitable for moderate-temperature refrigerant cycles
Function: Cool ammonia or CO₂ refrigerants in cold storage, food processing, or breweries.
Use Case:
Ammonia Condensers: SA179 tubes handle high-pressure ammonia vapor condensation.
CO₂ Transcritical Systems: Used in subcritical CO₂ refrigeration cycles.
Advantages:
High yield strength (≥180 MPa) resists pressure fluctuations.
Compatible with non-corrosive refrigerants under dry conditions.
Function: Condense steam or cool process fluids in ship engines or offshore platforms.
Use Case:
Desalination Units: SA179 fin tubes condense distilled vapor in multi-stage flash (MSF) plants.
Lube Oil Coolers: Remove heat from marine engine lubrication systems.
Advantages:
Cold-drawn seamless tubes resist vibration and mechanical stress.
Cost-effective for saltwater-cooled systems with proper coatings (e.g., epoxy).
