Extruded Fin Tubes
Base Tube O.D （mm） Base Tube Thickness (mm) Fin Height （mm） Fin Thickness（mm） Fin Pitch（mm） 10 mm ~38 mm 1.0 mm ~3.0 mm 6.35 mm ~ 32 mm 0.8 mm ~ 4.0 mm 2.1 mm ~ 6.0 mm Base Tube Material Fin Material Tube Length (Mtr) Carbon Steel ,Alloy Steel ,Stainless Steel, Copper Alloy Aluminum (Standard) or Copper ≤ 15Mtrs Extruded finned tubes provide the most stable performance over time as compared to the other fin types. The fin is rolled from an outer aluminum tube by a process using pressure to create a rolled "pressure bond" between the liner tube and fins. The aluminum fin material completely encloses the tube, except at the ends where a tube coating can be applied.
