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.
