Product Description

1. What is ASTM B163 Incoloy 825 Extruded Fin Tube with Aluminum Fin?

The ASTM B163 Incoloy 825 Extruded Fin Tube with Aluminum Fin is a premium bimetallic heat transfer solution engineered for extreme environments. It combines a seamless nickel-iron-chromium alloy base tube (ASTM B163 Incoloy 825) with integrally extruded aluminum fins through a high-pressure thermal process. This monolithic structure eliminates interfacial resistance, achieving 98% metallurgical bonding for unmatched thermal efficiency (45% higher than welded fins) and corrosion resistance in acidic, chloridic, and high-temperature applications up to 260°C (500°F).

2. Chemical & Mechanical Properties

Chemical Composition (Incoloy 825 Base Tube per ASTM B163)

Element	Content (%)	Key Function
Nickel (Ni)	38–46	Acid resistance
Chromium (Cr)	19.5–23.5	Oxidation resistance
Iron (Fe)	≥ 22	Matrix stability
Molybdenum (Mo)	2.5–3.5	Pitting resistance
Copper (Cu)	1.5–3.0	Sulfuric acid resistance
Titanium (Ti)	0.6–1.2	Stabilization
Carbon (C)	≤ 0.05	Weldability

Mechanical Properties (System Performance)

Property	Incoloy 825 Base	Aluminum Fin
Tensile Strength	≥ 586 MPa	186 MPa
Yield Strength	≥ 241 MPa	145 MPa
Max Service Temp.	540°C	260°C
Corrosion Resistance	★★★★★ (H₂SO₄, HCl, phosphoric acid)	★★★☆ (Anodized)
Thermal Expansion	14.0 μm/m·°C	23.6 μm/m·°C

3. Key Applications & Competitive Advantages

· Chemical Processing: Heaters in sulfuric acid regeneration units, HCl coolers.

· Marine & Offshore: Seawater-cooled condensers on ships/rigs (resists pitting/crevice corrosion).

· Waste-to-Energy: Boiler tubes in waste incinerators (handles HCl/SO₂ flue gases).

· Oil Refining: Crude oil preheaters in CDU/VDU units.

· LNG Processing: Cryogenic heat exchangers (-196°C to 200°C thermal cycling).

4. Why Engineers Prefer Our Extruded Tubes:
· Zero Thermal Barrier: 30% higher heat flux vs. welded fins (per HTRI Journal).
· Fail-Safe Design: Eliminates fin detachment risk in vibration/vacuum service.
· Lifecycle Cost Saving: 2x longer service life than carbon steel tubes in HCl vapor.
· Customization: Fin height (12–25 mm), thickness (0.8–2.0 mm), and helix angle optimization.
