New portable pipe wall thickness measuring techniques

A major inspection challenge facing the factory process industries is how to examine insulated piping for blockage and corrosion, especially for corrosion under the insulation and internal erosion. This problem is especially troublesome for the petrochemical, refining, utility: mining and paper industries. Responding to the need Lixi Inc. of the USA has developed a pipe-scanning inspection tool called the 'Profiler', which can quickly and easily scan an insulated pipe while the pipe is in service. Through proper calibration, the Profiler provides a double-wall thickness measurement of the pipe.
