Product Description
Finned tubes are supplied in applied L fin tube, LL fin tube, G fin tube, or Knurled L fin tube. All of which are helical wound applied fin tube, or extruded fin tube form. We can supply replacement finned tubes to suit your planned shutdowns or for emergency use.
Our Finned tubes are for use in oil refineries, petrochemical plants, power generating stations, and fertilizer and gas production plants
G Fin (Embedded Fin)
Application: High-efficiency fin for high operating temperatures
Upper limiting temperature: 400° C
Manufacture: A helical groove is formed in base tube displacing of material and fin is wound into the groove under tension followed by backfilling of the displaced material to lock the fin root into the tube
Fin materials: Aluminium
Base tube materials: Any readily machinable materia
L Fin (Wrapped Fin)
Application: Standard fin for low-temperature application where some degree of tube wall protection is required
Upper limiting temperature: 120° C
Manufacture: Fin foot is pre-formed into L shape and applied to base tube under tension. The adjacent fins abut one another giving a degree of base tube protection for less aggressive environments
Fin materials: Aluminium
Base tube materials: Any metallic material
LL Fin (Overlapped L Fin)
Application: Standard fin for low-temperature applications giving increased atmospheric corrosion protection of the base tube
Upper limiting temperature: 180° C
Manufacture: Fin foot is pre-formed into an LL shape (overlapped LL) and applied to base tube under tension. However, foot is pre-shaped to give overlap of one foot onto another thereby improving base tube protection and thermal contact area
Fin materials: Aluminium
Base tube materials: Any metallic material
K Fin (Knurled L Fin)
Application: Standard fin for medium-temperature applications, giving increased atmospheric corrosion protection to the outer surface of the base tube
Upper limiting temperature: 250° C
Manufacture: Fin foot is pre-formed into an L shape and applied to base tube under tension. Knurling tools both precede and follow the laying down of the fin foot so that the fin material is locked into the pre-knurled tube. This gives up to 50% greater thermal contact area than standard L fin and also ensures an airtight fin to tube bond, resulting in greater tube protection
Fin materials: Aluminium
Base tube materials: Any metallic material
Standard dimensions of applied fin tubes:
Base tube dia. (mm): 25.4, 31.8, 38.1, 50.5, 50.8
Fin height (mm): 9.5, 12.7, 15.88
Fin pitch: 236 to 433 fins/metre
Extruded Fin (Bi-metallic Fin)
Application: High-efficiency fins for higher temperature applications giving complete and permanent atmospheric corrosion protection of the base tube. Using over 40% more aluminium than the equivalent applied fin the extended fin is very robust and resistant to mechanical damage, allowing the finned tubes to be cleaned without damage using either steam or high-pressure water
Upper limiting temperature: 300° C
Manufacture: A carefully degreased core tube is fitted into an aluminium primary tube. This assembly is then fed into the triple-spindle finning head of the fin-extruding machine. Three special multi-disc packs extrude the aluminium tube into helical high fins while reducing the inner diameter to give firm pressure contact with the core tube
Fin materials: Aluminium
Base tube materials: Any metallic material
Standard dimensions of extruded fin tubes:
Base tube dia. (mm): 25.0, 25.4, 31.8, 38.1
Fin height (mm): 15.88
Fin pitch: 354, 393, 433 fins/metre
