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