In piping trade, what does the term "tapping" refer to?

In the piping trade, "tapping" specifically refers to the cutting of internal threads into the wall of a pipe. This process is essential when a fitting or a valve needs to be attached to the pipe, allowing for the connection of other equipment or the implementation of certain fixtures. By cutting threads internally, the tradesperson creates a surface that can securely hold a matching male-threaded fitting, enabling a leak-proof and robust connection.

While joining two pipes, measuring pipe lengths, and aligning pipe sections are all important tasks within the piping industry, they do not align with the specific definition of "tapping." Each of these tasks has its methods and tools, distinct from the threading process involved in tapping.
