LL Type Finned Tube (LL-Wound Fin Tubes) process: Fins made by wrapping base tube with fin strip, as in the case of type ‘L’ Tension Wound Type.


Description:


Manufacturing process: The fin strip (normally aluminum and copper) is folded into an L SHAPE and wound onto the base tube surface under tension. The feet of the fins are joined together and cover the finned surface.


Surface Protection

Both bare ends 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).


Accessories

Tube Support Box, Clamp or Spacer Box (Material: Aluminum, Zinc and 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 LL Type Tension Wound Finned Tube.


Packing:

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);

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 finning machines are designed and assembled by ourselves and we can offer you finning machines and all accessories etc...
  3. This method of manufacturing overlapped LL 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).
  4. The LL TYPE fin tubes can withstand a temperature of up to 170°C and provide a better corrosion protection by overlapping the feet of the L shapes. Maximum operating temperature: 170°C
