ASME SA179 Carbon Steel G Finned Tube Embedded Fin Tube For Air Cooler With ET Test

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.

3.Chemical Composition (Weight %):

4.Mechanical Properties:

5.Key Advantages

• 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.

6. Application of ASME SA179 Fin Tube

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

Industrial Refrigeration Condensers

• 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.

Marine & Offshore Condensers

• 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).
