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. All the goods 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. We provide Tube Support Box, Clamp or Spacer Box (Material: Aluminum, Zinc and Stainless Steel). The goods will be delivered when tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish at both ends of L Type Tension Wound Finned Tube.
Applications:
The common application fields are:
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;
Specifications:
KL Type Tension Wound Tube is combined with two different materials.

Competitive Advantage:
We have more than 10,000 square meters workshop, including 7 finning machines, daily production capacity up to 5,000 meters.
The finning machines are designed and assembled by ourselves (Reliance) and we can offer you finning machines and all accessories etc...
This method of manufacturing L tension 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.
KL TYPE fin tubes provide contact area between the fin strip and the tubes surface and protect the tube wall from atmosphere corrosion. This KL TYPE design is much economical than KL, even G-embedded type.
