ASME SA209 G-Type Embedded Finned Tubes: Durable & High-Efficiency for Air Cooler Heat Exchangers
Base tube material: ASME SA209 - compliant alloy steel, ensuring high strength and corrosion resistance. Fin material: Typically aluminum (customizable per project). Key chemical composition of base tube (meets ASME SA209 standards):
Element | C | Mn | P | S | Si | Cr | Ni |
% Max | 0.12 max | 0.2-0.6 | 0.035 max | 0.035 max | 0.1-0.3 | - | - |
Engineered for air cooler heat exchanger demands:
Property | Value |
Tensile Strength | ≥415 MPa |
Yield Strength | ≥205 MPa |
Elongation | ≥30% |
Aluminum Fin Properties:
Parameter | Value |
Fin Height | 8-16mm |
Fin Thickness | 0.4-0.8mm |
Fin Density | 7-14 FPI |
Thermal Conductivity | ≥200 W/m·K |
Our G-Type embedded finned tubes use a precision embedding process:
- Groove Machining: Laser-cut grooves on the SA209 base tube for fin insertion.
- Fin Bonding: Aluminum fins (or custom materials) are pressed into grooves, ensuring 99%+ contact rate for max heat transfer.
- Quality Inspection: 100% NDT (non-destructive testing) to verify fin integrity and tube strength.
- Heat Transfer Efficiency: Embedded fins boost heat exchange by 25-35% vs. standard fins (tested in air cooler simulations).
- Application Scenarios: Perfect for air cooler heat exchangers in petrochemical, power generation, and HVAC systems—ideal for cooling/hot gas recovery.
High Efficiency: Tight fin-tube contact minimizes thermal resistance.
Durability: SA209 base tube resists corrosion; embedded design avoids fin detachment.
Customization: Fins (material/thickness) and tube specs tailor-made for your project.
Q: Can these tubes handle high-temperature applications?
A: Yes—SA209 alloy steel supports up to 600℃ (custom materials for extreme temps available).
Q: What’s the warranty period?
A: 12 months for material/processing defects; lifelong technical support.
