Answer 1

The correct answer for the fitting of cast iron water pipe joints is often: Flange coupling

Explanation:

Brazing: Brazing is not commonly used for cast iron water pipes. It involves joining metals with a filler material that melts at a higher temperature than solder but lower than the melting point of the workpieces.
A socket: While sockets are used in some pipe systems, particularly with PVC pipes, they are not the primary method for joining traditional cast iron water pipes.
Flange coupling: Flange coupling involves connecting pipes using flanges—flat, circular discs with bolt holes. Cast iron water pipes often use flange joints for connecting sections of the pipe. Flange couplings provide a strong and reliable connection and are commonly used in various piping systems.
Welding: Welding can be used for joining pipes, but it is not the most common method for cast iron water pipes. Cast iron welding requires specific techniques due to the properties of cast iron.
