570, Piping Inspection Code

Designates a piping system that has been placed in operation as opposed to new construction prior to being placed in service or retired. A piping system not currently in operation due to a process outage is still considered to be in service. The operational stage of a piping system lifecycle that commences upon initial commissioning and ends when the piping system is finally retired from service or abandoned in place.

NOTE: 1 Does not include piping systems that are still under construction or in transport to the site prior to being placed in service or piping systems that have been retired.
NOTE: 2 Piping systems that are not currently in operation due to a temporary outage of the process, turnaround, or other maintenance activity are still considered to be “in service.” Installed spare piping is also considered in service; whereas spare piping that is not installed is not considered in service.
