Remote Visual Inspection devices allow inspectors to observe areas that would normally be inaccessible to visual inspection.
There are three categories of RVI devices. Videoscopes, rigid borescopes, and fiberscopes. The common factor between the three is a rigid insertion tube. They can be used to see into interiors of pipes, around tight corners, or in locations otherwise impossible to see.
Which tool is used will depend on the conditions and reporting requirements of the required inspection. When a choice is required, Focus NDT inspectors will select the right tool for the job, to ensure that all indications are identified and where required additional examination techniques are applied.
