The fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures.
The Embedded Fin Tubes are mainly used in places with higher temperature and where the working atmosphere is relatively less corrosive to the base tube.
G Fin Tubes or Embedded Fin Tubes are made of two main components, Base Tube and Fin Strip material.
Base Tube Material: Carbon Steel, Alloy Steel, Mild Steel, Stainless steel and tubes manufactured by ERW or Seamless Process
Fin Material: Aluminum, Copper
Embedded finned tubes offer several advantages:
-
Enhanced Heat Transfer: The embedded fin design increases surface area, improving thermal efficiency.
-
Durability: The secure embedding process ensures fins remain intact under high-stress conditions.
-
Versatility: Suitable for a wide range of temperatures and pressures, making them ideal for various industrial applications.
-
Compact Design: Efficient heat transfer allows for more compact heat exchanger designs, saving space and material costs.
Understanding the technical specifications of embedded finned tubes is crucial for selecting the right product for specific applications. These specifications include:
-
Fin Types: Common types include G-fin, L-fin, LL-fin, KL-fin, and extruded fins.
-
Tube Diameter: Typically ranges from 15.88 mm to 50.8 mm (5/8” to 2”).
-
Fin Density: Measured in fins per meter or inch, influencing heat transfer efficiency.
-
Working Temperature: Embedded finned tubes can withstand temperatures from 380°C to 420°C, depending on the fin type.
-
Corrosion and Mechanical Resistance: Varies by fin type, with embedded fins offering high mechanical resistance.
