Copper tubes rusting in two weeks?
Decent quality copper pipes shouldn't corrode THAT fast, it's what they used to use for... well for most everything until plastic pipes took over. What kind of insane environments are you subjecting it to such extremes that it's corrosion rate is weeks, and not years?
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. In some soft waters the general corrosion rate may increase to 12.5 µm/year, but even at this rate it would take over 50 years to perforate the same tube.
If you're THAT worried do what jdc122 said, treat it with lacquer. You shouldn't notice any serious corrosion on the copper for around a decade, unless there is some extreme causing it to corrode, like being submerged in an a highly acidic liquid.Edited by ZytheEKS - 6/30/13 at 5:46pm
