Embedded fins (G Fins) are made by winding aluminium or copper strip into a helical groove machined on the outer surface of the tube.
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.
1. MAXIMUM WORKING TEMPERATURE 400°C
2. ATMOSPHERIC CORROSION RESISTANCE LOW
3. MECHANICAL RESISTANCE RESISTANC MEDIUM
4. FIN MATERIALS ALUMINIUM, COPPER, CARBON STEEL
5. BASE TUBE MATERIALS Stainless Steel, Carbon Steel, Alloy Steel, Titanium, Copper, Duplex Stainless Steel, Inconel etc. (all material in the theoretical limit).
Standard: ASTM A210 / A210M : Seamless Medium-Carbon Steel Boiler and Superheater Tubes
Steel Grade: Grade A-1; Grade C
