Method and apparatus for measuring pipeline corrosion

摘要: An automatic corrosion measurement system and method enables rapid evaluation of on significant portions straight curved pipe sections other surfaces from several square inches to feet, using a laser instrument which projects light across scan area includes corrosion, detects reflected therefrom. A positioning mechanism advances the along surface permit large area, processor controls both operation mechanism. Automatic processing by converts condition signals into readily usable output in form displays, printouts or maps, for immediate use.
