Advantage of Inner grooved copper pipe:
1.High cleanliness and super brightness of inner and outer surface
2.Homogeneous and compact structure
3.High dimensional precision
4.High heat-exchange efficiency
5.Easy welding
6.Corrosion resistance
7.Easy to use and good formability.
Features for Copper tube:
It is extruded and well processed: joined by welding. Copper tube is harder than the plastic tube and has higher strength than other metal tubes, with the best flexibility.
1) Superior elongation
2) Good corrosion-resistance
3) Climate-hardiness
4) Electric
5) Heat conduction.
Process of the Copper tube:
Melting→casting→Extruding→Reducer→Drawing→Annealing→Packing
