What Does Internal Pipe Inspection Mean?
An internal pipe inspection is an analysis of the interior of a pipe to determine the interior level of corrosion or other issues present inside.
If a pipe is large enough for a person to enter, a direct, visual inspection is used. If the pipe is not large enough for a person to enter and inspect directly, the inspection is conducted by remote viewing.
An internal inspection is also the inspection of the interior of a water-based fire suppression piping system, either visually or remotely, every five years.
Trenchlesspedia Explains Internal Pipe Inspection
Internal pipe inspections are conducted as the need arises during trenchless construction.
For fire suppression systems, internal inspections are mandated every five years for fire suppression sprinkler systems by the National Fire Protection Association Standard NFPA 25. This means every organization that has a sprinkler system must have an internal pipe inspection every five years.
Inspections are conducted visually. Direct viewing may mean walking through the pipe or using a remotely operated vehicle (ROV), a robot with cameras specially designed for pipe inspections.
