CCTV (Closed-circuit television) crawler inspection is an industry go-to for pipe interior inspection. A CCTV camera is mounted on an IBAK crawler with a 1000' cable which transmits the high-resolution images to an above-ground computer and display. Continuous video is recorded as the crawler carries the CCTV unit through the pipe. The crawler can be stopped at any time and the CCTV camera can be rotated and the area of interest "zoomed" to reveal fine details.
The inner surface images of the pipe are recorded in real time for the period of the inspection and the videos are then analysed by the field engineer immediately. 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 6” (150mm) to 60” (1524mm) pipe diameters.
A laser profiler attachment can be added to enable precise inner dimensions of the pipe. Features such as welds, taps, branches and debris can be imaged and measured by the laser. Typically customers use it to accuratley measure pipe deflections caused by dents, wrinkles and freeze-bulges
