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.

* ISO Aluminum alloy is one of the most widely used non-ferrous structural materials in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum tube and aluminum tube is increasing day by day. The production process of aluminum tube generally adopts the production process of ingot heating - extrusion - finishing. For aluminum alloy materials that can be strengthened by heat treatment, quenching and aging treatment should also be carried out. Hard alloy and high magnesium aluminum alloy pipes generally adopt the production process of cold rolling extruded tube billet first, and then stretching out finished products.
