Definition - What does Internal Inspection mean?
Internal inspection is a method of assessing the condition of a pipeline which involves actual entry into the pipe to be inspected.
Internal inspections may be carried out by having qualified personnel physically enter the pipe or by using manually controlled mechanical equipment such as CCTV cameras or other similar remotely controlled equipment.
Trenchlesspedia explains Internal Inspection
Internal inspections are especially useful for identifying internal problems that may not have been picked up by other inspection methods.
These types of inspections are highly accurate since the location of defects can be precisely located and correctly identified from end to end. One of the main advantages of internal inspections is that it eliminates the need for potentially expensive excavations to reveal damaged pipe sections.
Internal inspections are particularly ideal for identifying:
- Blockages due to obstructions such as tree roots, grease, soil and other debris
- Internal cracks
- Pipe configuration and connections
- Internal corrosion
