    Description:

    Manufacturing process

    The fin strip (normally aluminum) is folded into an ‘L’ shape and wound on to the base tube surface under tension. The surface of base tubes must be knurled before tension.The feet of the fins are joined together and cover the finned surface.


    Protection of Ends

    Both bare ends of Knurled Footed Fin Tubes shall be Zinc or Aluminum metalized applied by an electro spray arc system coating.


    Acceptance Criteria

    API Standard 661(Air-Cooled Heat Exchangers for General Refinery Service) or the delivery conditions (TDC) of clients.


    Quality Test

    The Overlapped Knurled Footed Fin Tubes quality is assured by hydrostatic or pneumatic tests, eddy current tests and tensile tests in order to verify the mechanical bonding between inner and outer tubes.


    Accessories of KL type fin tubes

    Tube Support Box, Clamp or Spacer Box (Materials: Aluminum, Zinc or Stainless Steel).


    Delivery condition

    Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish at both ends of Overlapped Knurled Footed Fin Tubes.

    The desiccants are put into each package for continental transportation as well.


    Applications:

    The common application fields are:

    1. Heat exchangers units for power plant(electric, nuclear, thermal and geothermal power plants);
    2. High corrosive systems (condensers, evaporators, sea water desalinations, fertilizing, urea systems, ammonia, gas, corrosive acids);
    3. The petroleum, chemical and petrochemical industries;
    4. The food processing and refrigeration industries;
    5. Natural gas treatment;

    Competitive Advantage:

    1. We have more than 10,000 square meters workshop, including 7 finning machines, daily capacity up to 5,000 meters.
    2. The Knurled Footed Finning machines are designed and assembled by ourselves and we can offer you finning machines and all accessories etc...
    3. This method of manufacturing KL Footed Type enables us to place the finning on a very thin-walled tube with is particularly desirable when using high value alloys (titanium, stainless, copper, nickel).The tube can withstand a temperature of up to 150°C without the risk of atmospheric corrosion or thermal stress.
    4. KL TYPE fin tubes: the knurling process is strengthened the adhesion and reduce the tendency for fin loosening; and it is preferred when used in slightly more aggressive conditions. Maximum operating temperature: 250°C.
    5. After wrapped the fin strip, the fin foot is also knurled on the base tube to increase the bonding between tube and fin. For this reason, KL type of fin construction ensures better heat transfer characteristics than in the case of type L and LL.
