How do you connect copper pipe to steel pipe?

To safely connect copper and galvanized steel, you have two options. Since brass doesn’t react with either the copper or the zinc, one method is to make sure you have a threaded female end on both the copper and the steel pipes, and then connect the two by simply inserting a short threaded brass nipple between them.

Can you connect copper pipe to galvanized pipe?

Galvanized pipes should not be connected directly to copper pipes, period. The only time one can successfully replace a section of galvanized pipe with a section of copper is to make use of a dielectric union to ensure the metals do not have direct contact. Brass is an alloy of copper and nickel.

What fitting is required for copper with galvanized pipe?

You’ll need basic plumbing skills and tools, but the most important item you’ll need is a dielectric fitting. This fitting joins a copper pipe to a galvanized pipe, called a ‘union’.

Can you connect iron to copper?

Things You’ll Need Soldering iron to copper is not much different than soldering a piece of copper onto a copper fitting. The only real difference is that you will have to use a dielectric union at the point where the copper pipe joins the iron pipe.

What happens when copper touches metal?

Whenever you join copper water lines to galvanized steel pipe, you should be concerned about the corrosion caused by joining two dissimilar metals, called “galvanic corrosion.” An electrochemical reaction occurs that causes the steel pipe (in this case) to rust and clog up.

Can you join copper pipe to plastic pipe?

Interestingly you can join copper and plastic with a lot of the same fittings; a lot of people don’t realise you can join a bit of plastic pipe with a compression fitting. Once you’ve inserted the liner the nut goes over the end of the pipe followed by the copper olive and then the fitting itself.

How do you connect galvanized pipes without threads?

Use a stainless steel coupling if the galvanized pipe is in a damp position to avoid problems associated with rust. Unthreaded galvanized pipe connects together using a coupling. Connecting together galvanized pipes that are non-threaded uses a coupling that creates a sealed joint.
