 Copper Water Tubes
Copper tubes have been used to distribute drinking water within buildings for many years, and hundreds of miles are installed throughout Europe every year.The long life of copper when exposed to natural waters is a result of its thermodynamic stability, its high resistance to reacting with the environment, and the formation of insoluble corrosion products that insulate the metal from the environment.The corrosion rate of copper in most drinkable waters is less than 2.5 µm/year, at this rate a 15 mm tube with a wall thickness of 0.7 mm would last for about 280 years.
