Product Description

{}{}Tension Wound Fin Tubes

The Tension Wound Fin means the fins wrapped tightly around the tube and welded or stapled at the ends of tubes to hold the form. Tension Wound Fins can also be solder-coated to strength the corrosion resistance. Tension wound fin works especially prefer with fins and tubes that are use the same material.

"L" Footed Fin tubes

"L" Footed Fin has a lip at the base which is tension wound around the tube. This increases the connected area and increases the heat transfer connect area between the fin and the tube and decreases the exposed joints at the fin base. 

"LL" type fin tubes also called Overlapped "L" Fin tubes

The Overlapped "L" fin design has interlocking fins that are wound together to prevent movement and separation. The fin protects the entire tubes, so the designation works well for the applications where corrosion is a factor.

KL fin tubes also named knurled finned tubes

Manufactured method is exactly as the 'L' finned tube except that the base tubes are knurled before application of these 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.

G Fin Tube (or Embedded Fin Tube)

G type embedded spiral finned tube is processed from a certain width in the steel pipe and spiral groove depth, then inlays the ribbon on the steel pipe by the equipment. In winding process, as the pre-tightening force to a certain extent so the strip will be firmly in the spiral groove, to ensure there is a certain contact area between steel band and steel pipe. In order to prevent the strip spring falling off the light tube, the two ends of the steel strip need to weld onto the steel pipe. In order to set easily, there should be a certain clearance between steel belt and spiral groove. If the clearance is too small the setting process will be difficult to proceed smoothly. In addition, the steel belt of winding there will always be a certain amount of rebound, which makes it cannot very good joint among the steel belt and spiral groove bottom. Inlaid fins can be conducted on general equipment, and they cost little. With the advanced production equipment, slotting embedding technology is advanced, from stable, embedded and firm, pulled off force not less than 70 n, the allowable temperature can reach 400 ℃, has the strong ability of temperature resistance and thermal shock, widely used in petrochemical air cooler.
