What Does Borescope Mean?

A borescope is an optical device that enables operators to view remote parts of a system in a non-destructive manner. It is especially useful in trenchless rehabilitation methods to inspect a pipeline for damage such as cracks, tree root intrusion, water infiltration, corrosion etc. without having to excavate the area where the pipeline suspected to be the cause of damage is located.

The use of a borescope is cost-effective and precise, making it a great tool for trenchless rehabilitation methods.


Trenchlesspedia Explains Borescope

Borescopes come in two types, namely a rigid borescope, and a flexible borescope. It typically consists of a rigid working length, a light source for illumination, an optical system consisting of a relay lens system, a rod lens system, a fiber optic image guide, a camera, an eyepiece and a monitor to view the image transmitted.

Rigid borescopes consist of the optical device connected to a rigid tube and are great for straight pipes, but they cannot be used where bends and curves are likely to be encountered.

Flexible borescopes are connected to the eyepiece by a flexible tube consisting of optical fibers and are very useful where plenty of bends and curves are expected. The ability to maneuver the camera is important in order to pinpoint problem areas for determining the kind of damage present and choose a method for rehabilitation.
