Product Description
Extruded fin tubes with a base tube made of ASTM B163 Incoloy are specialized components designed for high-performance heat transfer applications. Incoloy, a family of nickel-chromium-based superalloys, provides excellent resistance to oxidation, corrosion, and high-temperature environments, making it an ideal choice for demanding applications.
Key Advantages
High Thermal Efficiency
- Improved Heat Transfer: The extruded fins increase the surface area, enhancing heat transfer efficiency
- Effective Bonding: The extrusion process ensures strong bonding between aluminum fins and Incoloy base tube
Durability and Longevity
- Excellent corrosion and oxidation resistance for harsh environments
- Robust construction maintains mechanical integrity under stress
Versatility
- Suitable for petrochemical, power generation, chemical processing, oil and gas, marine applications
- High-temperature capability for extreme operating conditions
Construction Features
- Extrusion process creates strong mechanical bond between aluminum fins and Incoloy base tube
- Enhanced surface area improves heat transfer efficiency
