Pipe network (pipe)

Piping linking different units of the plant is considered as "pipe network (pipes)" (for example, a pipe linking an unloading unit and a storage unit, or linking a storage unit and a process unit), as well as pipes feeding the flare. Piping staying inside a unit (for example, inside a storage farm, or between two process equipment of the same process unit) is not considered as "pipe". They are integral part of the equipment to which they are linked.
