  3. Tube (fluid conveyance) - Wikipedia

    en.wikipedia.org/wiki/Tube_(fluid_conveyance)

    A tube and pipe may be specified by standard pipe size designations, e.g., nominal pipe size, or by nominal outside or inside diameter and/or wall thickness. The actual dimensions of pipe are usually not the nominal dimensions: A 1-inch pipe will not actually measure 1 inch in either outside or inside diameter, whereas many types of tubing are ...

    When the water meter is located at that alternative position, the pipe section that connects the water main to the water meter is the communication pipe, and the section that connects the water meter to the building isolation valve is the supply pipe. [9] [27] Lead service lines can exist in one of these scenarios: the communication pipe ...
