Closed-circuit television (CCTV) inspection is the standard straightforward approach for pipe interior inspection. A CCTV camera is mounted on a stiff cable (the same cable used for I-PIT Tools) and is pushed through the pipe to a distance of >300 feet.
The inner surface images of the pipe are recorded for the period of the inspection and the images are then analysed by the field engineer real time. CCTV inspection services are ideal for monitoring pipe constructed with various materials, including metal, concrete, plastic and fibreglass. This particular CCTV system works best in 2” to 4” pipe diameters.
