U Bend And Finned Tube

Helically Wound High Fin Tubes 'L' Finned Tube å?¾ç??3.png 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: 150â?? Atmospheric Corrosion Resistance: Acceptable Mechnical Resistance: Poor Fin Materials: Aluminum, Copper Tube Materials: No theoretical limits. 'LL' Finned Tube å?¾ç??3.png 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: 180â?? Atmospheric Corrosion Resistance: Acceptable Mechnical Resistance: Poor Fin Materials: Aluminum, Copper Tube Materials: No theoretical limits. 'KL' Finned Tube å?¾ç??3.png 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: 260â?? Atmospheric Corrosion Resistance: Acceptable Mechnical Resistance: Acceptable Fin Materials: Aluminum, Copper Tube Materials: No theoretical limits. 'G' Embedded Finned Tube å?¾ç??3.png (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: 450â?? Atmospheric Corrosion Resistance: Poor Mechnical Resistance: Acceptable Fin Materials: Aluminum, Copper, Carbon Steel Tube Materials: No theoretical limits. Extruded Finned Tube å?¾ç??3.png 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: 150â??

Process: the extruded fin tube is bimetallic combined with integral aluminum fins on the outside surface. The base tube is inserted inside the aluminum tube and both tubes are passed through extrusion machine. The tight mechanical bond between aluminum tube and inner base tube is accomplished during the fining work and same time makes the n steel, low-alloy steels, stainless steel , brass , copper , cooper-nickel alloys , aluminum bronze , nickel alloys , titanium etc... Fin materials: aluminum 1060f, aluminum 6063-o, aluminum1100-o, copper Tube od: 16 mm to 50.8mm. Tube wall thickness: 1mm min Tube entire length: 16, 000mm max. Other lengths are also available to accommodate customer's need. Fin thickness: 0.3mm to 0.7mm, 0.4mm at average. Fin height: 16mm max. Fin pitch (mm): 6 fpi to 12fpi. As per purchase quantities
