Seamless Tension Wound KLM Type Structural Aluminum Tubing
A192 SMLS Carbon Steel , OD25X2.11WT LL Overlapped Type Aluminum Cooling Fin Tube
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.Both bare ends shall be Zinc or Aluminum metalized applied by an electro spray arc system coating on surface. It suits various area such as 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
