'pipefitting' originates from the combination of 'pipe' and 'fitting', where 'pipe' refers to a tube for conveying fluids and 'fitting' refers to the parts used to connect pipes.

'pipefitting' evolved from the need to describe the specific task of assembling and installing pipes and their connections.

Initially, it referred to the general task of assembling pipes, but over time it has come to specifically denote the trade and skill involved in this work.
