A layer of nickel about 5 to 50 mils in thickness is plated over copper pipes that are used in the water-cooling system of a data processor. This layer seals any possible defects in the underlying copper piping or in the brazed or soldered connections. The nickel has good adhesion to the copper; it is mechanically stronger than the copper, and it is galvanically protected by the copper. A large piping assembly is electroplated as a unit without significant masking. The coating has a dull gray appearance that does not require further finishing operations.
