SA214 ERW Carbon Steel , OD25.4X1.5WT KL Type Aluminum Refrigeration Tube



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.


Application of SA214 ERW Tubes: For high, middle, low pressure boiler and pressure purpose

Surface treatment: Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting



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. The accessories with this fin are Tube Support Box, Clamp or Spacer Box (Material: Aluminum, Zinc and Stainless Steel). It suits various area such as The common application fields area, Heat exchangers units for power plant(electric, nuclear, thermal and geothermal power plants), High corrosive systems (condensers, evaporators, sea water desalinations, fertilizing, urea systems, ammonia, gas, corrosive acids), The petroleum, chemical and petrochemical industries, The food processing and refrigeration industries, Natural gas treatment;



Both bare ends shall be Zinc or Aluminum metalized applied by an electro spray arc system coating. The desiccants are put into each package for continental transportation as well.


Acceptance Criteria:

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



Knurled footed tube is combined with two different materials.

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.
