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

Quality Control & Guarantee System of Copper tube :
1) Full Controlled by ISO system
2) Chemical analysis before casting
3) Eddy current testing
4) Dimension check
5) Miscellaneous tests
6) Tensile test (Tensile strength, yield strength, elongation)
7) Expansion test
8) Hardness test
9) Microscopically examination

Applications for the Copper tube:
1) Air Conditioner and Refrigerator
2) Water tube service and distribution
3) Fire Protection, Solar, Fuel/Fuel Oil
4) Natural Gas, Liquefied Petroleum (LP)Gas
5) HVAC, Snow Melting, Drain, Waste, Vent Piping
6) Re-drawing usage
