ASME SB163 N04400 Embedded Fin Tube With Alminium Fin For Air Cooler And Gas Reboiler

1. Base Tube Material: Monel 400 (UNS N04400)

Composition:

• Nickel (Ni): 63–67%

• Copper (Cu): 28–34%

• Iron (Fe): ≤2.0%

• Manganese (Mn): ≤2.0%

• Carbon (C): ≤0.3%

• Sulfur (S): ≤0.024%

Mechanical Properties:

• Tensile Strength: 550–780 MPa
• Yield Strength: 240–550 MPa
• Elongation: 35–50% (at 50 mm gauge length)
• Hardness: 70–90 HRB (Rockwell B)

Temperature Limits:

• Continuous Service: Up to 600°C (1112°F)
• Low-Temperature Use: Maintains ductility down to -200°C (-328°F).

Corrosion Resistance:

• Resists chloride-induced stress corrosion cracking (SCC), pitting, and crevice corrosion.
• Compatible with sulfuric acid (<50% concentration), hydrochloric acid (<20%), hydrofluoric acid, and alkalis.

2. Fin Material: Aluminum (Al)

• High Thermal Conductivity: Aluminum’s superior heat transfer efficiency enhances the overall heat exchange rate.
• Lightweight: Reduces the total weight of the assembly while maintaining structural integrity.
• Cost-Effectiveness: Offers a balance between performance and affordability compared to exotic alloys.
• Corrosion Resistance: Naturally forms a protective oxide layer, suitable for moderate environments (when combined with Monel 400, it extends applicability to harsher conditions).

3. Design Features

• Embedded Fin Technology: Aluminum fins are tightly bonded to the Monel 400 base tube via mechanical or hydraulic expansion, ensuring optimal thermal contact and durability.
• Customization: Available in various fin densities, heights, and tube lengths to meet specific heat transfer requirements.
• Application Flexibility: Suitable for heat exchangers, condensers, boilers, and cooling systems in industries like petrochemical, power generation, and marine engineering.

4. Application

• Marine & Offshore Systems
• Desalination Plant Heat Exchangers
• Sulfuric Acid (H₂SO₄) Coolers
• Sour Gas (H₂S) Reboilers
• Steam Condensers in Geothermal Plants
• Flue Gas Waste Heat Recovery
• Ammonia (NH₃) Evaporators
• Heat Recovery Ventilators (HRVs)

5. Advantages

Durability: Monel 400 resists pitting, crevice corrosion, and stress corrosion cracking.

Efficiency: Aluminum fins maximize surface area for rapid heat dissipation.

Adaptability: Performs reliably in extreme temperatures and corrosive media.
