If you do connect copper pipe to galvanized pipe, you will need a dielectric coupling or else the galvanized pipe will corrode. Same with connecting galvanized pipe to brass fittings. Brass is an alloy that contains copper and therefore the same electrolytic properties will exist unless a dielectric coupling is used. Hope that helps you out.
There are copper fittings that will connect to galvanized.
Yes. Use a threaded fitting, male or female as needed on the copper and screw the galvanized into it.You must use a dielectric fitting to connect copper to galvanized pipe. If you don't, a galvanic reaction will occur and the piping will corrode and leak. You can use a Dielectric Union or a Threaded Brass fitting to join the two types of piping together.UNIONS can leak the best answer would have been a dielectric nipple
usually copper corrodes from a chemical process known as "galvanic reaction". This is caused when copper is touching dissimilar metal such as steel or galvanized. a di-electric union is used to prevent this. further questions Jeff at jlgprop@yahoo.com
Yes
There is no chemical reaction that will happen if galvanized pipes are connected to copper pipes via a brass intermediary. The reason is that brass does not react to either copper or zinc, the mineral used to galvanize metal pipes.
yes. Copper to Galvanized must have a dielectric fitting to avoid a galvanic reaction causing corrosion and eventual leaks.
Heat speeds up chemical reactions. As corrosion is a chemical reaction, copper pipes at a higher temperature will corrode faster
Because you will then get a 'galvanic reaction'.
A threaded copper fitting on the copper side, male or female, and the galvanized is screwed into it.
Yes! The best copper-to-galvanized connection is made using a brass nipple in between the two dissimilar metals. The nipple should be a minimum of 2 1/2" long (preferably six inches long). Bronze is an alloy (copper + tin). Brass is an alloy (copper + zinc).
Steel will corrode as the iron in it is more reactive than copper.
"Rust" is the result of a reaction between iron and oxygen. Copper has no iron in it, so does not rust. It can corrode, though, and yield a bright whitish-blue material.
