Pipework → It is formed from "pipe" (from Old English "pipa", meaning a tube or hollow cylinder) and "work" (from Old English "weorc", meaning activity or labor). The term "pipework" refers to the system or arrangement of pipes used for conveying fluids or gases.
Think of a 'tube' ('pipe') that is part of a system of 'activity' ('work') — that's what pipework means.
