A pitch pipe.
No pipe dope is to be used on the brass seats they will seat dry.
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.
If a steel pipe is fitted with a brass tap, it is the brass tap that will get corroded.
Lead wipe a brass nipple into the lead pipe and then use a female adapter x PVC on the brass threads
In a decent plumbing supply store.. I had one brass wrench I used exclusively on gas piping to prevent sparks
There should be a nut around the chrome pipe holding it to the brass. Loosen the nut and pull the chrome pipe out.
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
Yes, it is still a pipe thread. The pipe dope is there to fill in the gaps in the thread. It is impossible to machine the treads close enough in pipe to not need something in the threads to make a seal.
No, brass cannot be used as a dielectric union between copper and black iron pipe. Dielectric unions are typically made of materials that are not electrically conductive, such as plastic or rubber. Brass is a conductive material and would not provide insulation against galvanic corrosion between copper and black iron pipe.
yes
