This refers to the network of pipes, fittings, and valves used to convey fluids (liquids, gases, steam, or slurries) from one point to another within an industrial or commercial facility. If the charpente is the skeleton, the tuyauterie is the circulatory system (the veins and arteries) of the facility.
