When connecting a galvanized piping system to a copper system, a dielectric waterway or dielectric union should be installed to stop galvanic corrosion. Galvanized metal pipe is seldom used anymore. Black steel pipe is manufactured as seamless which makes it a better type for gas transportation.

Suitable for restore work (ie work in the repair process, the one injury to the metal floor to be protected place, so long as the repaired floor might be re-coated). Pin leaks can also be a problem with copper pipes if there are large temperature fluctuations. Threaded galvanized pipe refers to welded tube which undergo degreasing,rush removal,phosphorization,zand drying processes earlier than galvanization.
