Yes, either by sweating it or with the right fitting on the copper for the brass to screw on.
Yes by soldering , brazing, adapters such as Flagg flow TP fittings , Flaire, screwed , Mechanicl joints
By threading the steel piping and then screwing on the type of valve you need for the application
Only recommended if you use a coupling that does nor let them directly contact. An Acorn, Qwest or Sharkbite coupling.
It's ok as long as none touch each other. Use a coupling with plastic or rubber centre.
In order to connect a chromed steel pipe to a copper pipe, you will need a brass fitting. These two pipes will not fit into each other otherwise.
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.
NO but you will need some type of sealent OR braze or soldering
Nothing all one has to do is look at the many installations of steel pipe and brass valves
Yes, you can either solder them or fit mechanical (threaded) fittings.
Plastic pipe does not rust, brass does not rust, copper does not rust. Stainless steel does not rust, lead pipe does not rust.
If a steel pipe is fitted with a brass tap, it is the brass tap that will get corroded.
Easiest way to connect lead to copper /brass is a wiped joint consisting 40 - 60 solder alloy as this gives a longer pasty range
Absolutely, positively, YES as both are non ferrous metals and there is no possibility of galvanic corrosion or electrolytic action taking place. Presuming your taking about RED BRASS as opposed to Yellow
There are instances when corrosion occurs at the junction of a carbon steel pipe and a brass valve. This is often the result of a pipe threading failure.
No! That will create intergranular corrosion
Because if you join copper (the pipe) directly into steel (the radiator) the electrolytic difference is so great they would corrode very quickly. By using brass between them you reove this risk.
