There is a coupling that almost all plumbing stores should have(including lowes). Its name can vary but is commonly called a dresser coupling or a raybolt.
Plumbing pipe threads are squared and conduit pipe threads are tapered.
Female pipe thread features an internal tapered or straight thread design that allows it to connect with male pipe threads. The internal threads are typically cut into the inside of a fitting or pipe, creating a snug fit when mated with a male counterpart. The most common types are NPT (National Pipe Tapered) and NPS (National Pipe Straight) threads, distinguished by their taper and shape. Female threads often appear as a smooth opening with visible grooves from the threading inside.
The threads
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
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.

Water pipe threads are tapered, electrical pipe is not tapered.
No, NPT threads are not compatible with NPSM threads. A pipe with NPT threads tapers slightly, while an NPSM-threaded pipe does not taper.

Yes
Taape or joint compound on the threads the same as any other pipe fitting, but not on the threads where the two halves connect.
NPT = pipe Briggs standard = Pipe NFT and NFC and ASAE = bolt
Steel pipe that is schedule 40, means that the steel pipe has a certain amount of threads on it. It also means that it can't be longer than about 10 feet.
Traditionally, Iron Pipe Size, but can also mean that it has male pipe threads (threads on the outside of the pipe).
To connect PVC to galvanized pipe, you can use a PVC to threaded adapter. This adapter has a female threaded end that can be screwed onto the male threaded end of the galvanized pipe. Make sure to use Teflon tape on the threads to create a tight seal and prevent leaks.
