ASME SB163 N04400 G-Type Embedded Finned Tubes: High - Efficiency Solution for Air Cooler Heat Exchangers
The base tube material is N04400 (Monel 400), and fins are made of aluminum. The chemical composition of N04400 meets ASME SB163 standards, with key elements as follows:
Element | Cu | Ni | Fe | Mn | C | Si | S |
% Max | 28-34 | 63-70 | 2.0 max | 2.0 max | 0.3 max | 0.5 max | 0.01 max |
2. Performance & Mechanical Properties
- Thermal Performance: The embedded AL fins significantly enhance heat transfer efficiency. For air cooler heat exchangers, it can improve the heat exchange rate by up to 30% compared to ordinary finned tubes in similar working conditions.
- Mechanical Properties: The base tube has a tensile strength of 550 - 750 MPa, yield strength ≥ 240 MPa, and elongation ≥ 30%. The fin - tube combination ensures good resistance to vibration and pressure in air cooler operations.
Property | Value |
Tensile Strength | 550-750 MPa |
Yield Strength | ≥240 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 adopt an advanced embedding process. First, precise grooves are machined on the N04400 base tube. Then, aluminum fins are firmly embedded into these grooves, followed by strict quality inspection. This process ensures strong fin - tube bonding, excellent heat transfer, and long - term stability.
Ideal for air cooler heat exchangers in industries like petrochemical, power generation, and refrigeration. It can efficiently cool or condense media such as process gases, steam, and refrigerants, ensuring stable operation of industrial systems.
- High Efficiency: Optimized fin structure and material combination for superior heat transfer.
- Durability: High - strength base material and reliable fin - embedding process for long service life.
- Corrosion Resistance: N04400 base tube resists corrosion in harsh environments, and aluminum fins are suitable for air - side conditions.
Q: Can these tubes be customized for specific projects?
A: Yes. We offer customization in terms of size, fin density, and material grades to meet diverse customer needs.
Q: What is the service life of these finned tubes?
A: Under normal operating conditions in air coolers, the service life can reach over 10 years, depending on the specific working environment.
