High Precision Finned Tubes
Helically Wound High Fin Tubes 'L' Finned Tube The strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maximising the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube. Maximum Working Temperature: 150℃ Atmospheric Corrosion Resistance: Acceptable Mechnical Resistance: Poor Fin Materials: Aluminum,Website:, Copper Tube Materials: No theoretical limits.'LL' Finned Tube Manufactured in the same way as the 'L' fin type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of tube is often used as an alternative to the more expensive extruded type fin in corrosive environments. Maximum Working Temperature: 180℃ Atmospheric Corrosion Resistance: Acceptable Mechnical Resistance: Poor Fin Materials: Aluminum, Copper Tube Materials: No theoretical limits.'KL' Finned Tube Manufactured exactly as the 'L' fin except that the base tube is knurled before application of the fin foot. After application the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between the fin and tube resulting in improved heat transfer characteristics. Maximum Working Temperature: 260℃ Atmospheric Corrosion Resistance: Acceptable Mechnical Resistance: Acceptable Fin Materials: Aluminum, Copper Tube Materials: No theoretical limits.'G' Embedded Finned Tube(Embedded Fin)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. Maximum Working Temperature: 450℃Atmospheric Corrosion Resistance: PoorMechnical Resistance: AcceptableFin Materials: Aluminum, Copper, Carbon SteelTube Materials: No theoretical limits.Extruded Finned Tube The strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maximising the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube. Maximum Working Temperature: 150℃ Atmospheric Corrosion Resistance: Acceptable Mechnical Resistance: Poor Fin Materials: Aluminum, Copper Tube Materials: No theoretical limits.Production CapabilityBase Tube OD:From 5/8" (15.88mm) to 2" (50.8mm)Fin Height :From 1/4" (6.35mm) to 1" (25.4mm)Fin Pitch :From 5 fins per inch to 12 fins per inch(196 fins/metre to 473 fins/metre)Fin Thickness:From 0.012" (0.30mm) to 0.031"(0.76mm)Base Tube Material:Dependent on fin typeFin Material:Aluminium, Copper or Cabon SteelFin Types :L, LL, KL, G, Extruded
