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...

Aluminium fin tubes Can quote for aluminium fin tubes for air cooled heat exchangers in various materials like carbon steel, stainless steel, and non ferrous materails

Copper Low Finned Tubes Used for Heat Exchangers and Chillers and Condensors and Boilers .

Aluminium fins are formed from a bimetallic tube consisting of a base tube and an aluminium muff tube. The fins are formed on a cold rolling process from the wall thickness of the aluminium muff tube. Extruded fin gives very good corrosion protection to the base tube, as the base tube is not visible to the atmosphere inbetween the fins. Maximum operating temperature for extruded finned tube is 325 deg C. Fin Material - Aluminium (or) Copper Tube Material - No theoretical limit

U Bend And Finned Tube: ACC (aluminum clad copper) tube ACC tube has an outer layer of antirust 3003 aluminum alloy and inner layer of oxygen-free copper. The copper-aluminum interface achieves metals bonging among atoms, popular saying: metallurgy bonding. ACC tube combines the excellent moment decalescence capability of copper with the excellent heat-sinking capability of aluminum. Thus, ACC tube owns good heat-transmit performance, which can be widely applied in air conditioner, refrigeration, dehumidifier and so on. The heat exchanger, adopting ACC tube, completely eradicates the electrochemistry decays between copper tube and aluminum of traditional heat-exchanger. Greatly reduces the recession of energy efficiency ratio, provides key material for making long-effect air conditioner, and saves more than30% purchase cost for manufacturer. Over millions of air-conditioners have been put to market. Anti-corrosion and heat exchange performance can meet the requirements. NOTE : All index and parameters achieve related standards after testing the air-conditioner made by ACC tube, which has run for over 5 years. ACC tube basic performance ACC tube weight ratio : CU/AL30/70 Volume Ratio : CU/AL10/90 Tension strength : 115Mpa Elongation : 35% Expanding : 40% Density : 4.3

Spiral wound finned tubes or crimped finned tubes spiral wound on the base tube, without welding, but spot welding at the end. Material of spiral wound finned tube or crimped finned tube: the finned strip can be copper, carbon steel, stainless steel, non-ferrous metal tube and fin, or it can be root welded or completely welded. Spiral crimped stainless steel finned tube. Spiral tension wound finned tubes for air coolers. Due to the high corrosion resistance of stainless steel, when the environment has certain corrosivity or cleanliness, such as climate industry, heating, drying and cooling, stainless steel crimped fin tubes can be widely used. Usually used for finned tube heat exchangers. The maximum working temperature is 180 â??. Compared with L-shaped finned tubes, spiral wound finned tubes or crimped finned tubes provide higher air side turbulence and heat transfer due to fins curling. Material standard of crimped fin tube: both base tube and fin can be carbon steel and stainless steel Carbon steel: A179, A192, SA210 Gr A1/C, A106 Gr B Stainless steel: TP304/TP304L, TP316/TP316L
