Has Pipe Become Deformed?

After a number of years, due to overlying load and material degradation, pipes lose the circular shape and tend to flatten out, becoming “oval”.

This has several consequences, like the flow capacity is impaired, and pipe slip lining is not possible as a pipe rehabilitation option.

The only way to measure this “ovality” is to attach a laser profiler to the pipe video inspection camera. As the camera passes through the pipe, a laser ring is projected onto the surface of the pipe, and the shape of the ring is recorded for shape analysis. This is called pipe laser profiling.
