Pipes inspection tools

The inspection of piping is very well covered in the practical American Petroleum Institutes (API) Recommended Practice 574, Inspection of Piping, Tubing, Valves, and Fittings. [20] The recommended practice addresses the description of piping components, causes of deterioration, frequency of inspection, inspection tools, inspection procedures, and record keeping. 

Pipeline inspection tools depend on the type of pipe and the level of details which the owner chooses to budget for during the inspection. One of the most cost-effective... 

The corrosion inspection and wall thickness measurement of pipes was performed in the classical way both on film and on the monitor using simple software measuring tools. Additionally algorithms were developed for an interactive, computer supported evaluation. 

However, most internal repair methods are used for low operating pressure pipelines and only to restore leak tightness (Toutanji and Dempsey, 2001). Also, these internal repair systems are considered to cause reductions in the inside diameter of pipelines that may hinder the ability to clean and inspect them using traditional tools. Thus, the use of composite materials for internal repair of pipes presents a number of difficulties that have yet to be fully explored.
