Introduction:
The aluminum fin strip is tension wound and placed into a groove cut into the tube. And all the goods are Zinc or Aluminum metalized applied by an electro spray arc system coating, and put into each package for continental transportation as well. When the Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish at both ends of G-Fin Embedded Finned Tube it will suits the delivery condition. Besides we provided Tube support box, clamp or spacer box (Materials: Aluminum, Zinc and Stainless Steel).
It has various uses in 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;
G Fin Fluted Depth:
Appr. 0.4mm.
