Applications

The copper tubes are made of pure electrolysis copper. They are precise in size and smooth on surface. 

Besides, they are of good heat conductibility. Furthermore, they are reliable in quality. Thus, they are widely 

used for heat exchangers, radiators, coolers, electro-heat-up pipe, air conditioner and refrigerators. The straight pipes can be used for oil transportation, brake 

pipes, water pipes and gas pipes for construction

Advantages :

100% recyclable  Copper stands alone as an engineering

material that can be recycled over and over without degradation in content or properties

 Economical.The combination of easy handling, forming

and joining permits savings in installation

time, material and overall costs

   Lightweight  Copper tube does not require the heavy thickness

of ferrous or threaded pipe of the same internal diameter

  formable.   Because copper tube can be bent and formed, it

is frequently possible to eliminate elbows and join easy to join  Copper

tube can be joined with capillary fittings.These fittings save material and make smooth, neat, strong and 

leak-proof joints.
