There is a tool called easy out.
With a extractor
Traditionally, Iron Pipe Size, but can also mean that it has male pipe threads (threads on the outside of the pipe).
An inside pipe wrench also called a pipe extractor. It drives into the broken off pipe and is then turned with a crescent wrench.Normally a extractor or inside pipe wrench does not work removing a pipe . What works best is the use of a hack saw blade and a chisel to cave in the threads after the threads are cut.. BECAREFUL not to cut into the fitting threads
Only apply thread sealant to the MALE threads of the pipe.
To properly use Teflon tape for sealing pipe threads, wrap the tape around the male threads in a clockwise direction. Make sure to overlap the tape by about half its width and wrap it tightly. This will help create a tight seal and prevent leaks when connecting the pipes.
Depends. What it is broke off in. Sometimes you can use a hacksaw blade and cut through the male part just through the threads and then pry out the piece. I have sometimes had to make three cuts and take the pipe out in sections. If it is in another pipe and you can heat the end, this will loosen the pipe and an E Z out or extractor can be used to back out the piece. If it is a small pipe that is too small for a hacksaw blade, if you are very careful and lucky, you can drill out most of the pipe to the threads in the female part and then peal out the thread or rethread the female side which will clean out the threads.
Compression uses a ferrule or brass ring around the pipe that is compressed by the nut into the pipe and against the fitting. There is no such thing as Female Pipe Threads. There are Male and Female fittings, the pipe is the Male side and the fitting is Female. The Male goes inside of the Female. They both have pipe threads. Pipe thread, Compression, and Flare all have different thread pattern so that they cannot be mixed. They all do different jobs.
Faucet supplies are 1/2" NPS vs. pipe 1/2" IPS. they are 2 different threads.
A pipe fitting that has both external and internal threads is called a "coupling." Couplings are used to connect two lengths of pipe, with one end having female threads (internal) to receive a male threaded pipe and the other end having male threads (external) to connect to another fitting or pipe. This design allows for versatile connections in plumbing and piping systems.
IPS (Iron Pipe Size) threads and NPT (National Pipe Taper) threads are not the same, although they are related. IPS is a sizing standard for pipes, while NPT refers specifically to the tapered threading used on those pipes. NPT threads are designed to create a seal when tightened, whereas IPS primarily refers to the pipe's nominal size. However, IPS pipes often use NPT threads for connections, making them compatible in many applications.
Male Iron Pipe Adapter. This means it has male pipe threads and will adapt to either PVC pipe, Poly pipe or a few other types of pipe to make a transition from threaded pipe to something else.
Pipe dope is a paste-like substance that is applied to pipe threads before connecting them, providing a seal by filling in gaps and preventing leaks. Teflon tape, on the other hand, is a thin, flexible tape that is wrapped around pipe threads to create a tight seal by lubricating the threads and preventing leaks. Both are effective in sealing pipe joints, but pipe dope is more commonly used for larger pipes and Teflon tape for smaller pipes.
