Pipe System (or Piping System)

 

The primary piping, secondary containment, leak detection devices, tubing, including suction line drop tube, flanges, bolts, gaskets, valves, fittings, flexible connectors, the pressure−containing parts of other components such as expansion joints and strainers, and devices that serve such purposes as mixing, separating, distributing, metering, or controlling flow, and any core components which allow the piping system to function as intended and in accordance with the installation requirements.

 

Note: For a typical underground system, the pipe system would be from   the point of connection at the tank to the connection to the dispenser, immediately downstream of the emergency shut−off valve.
