Boilers are found in most process plants and utilities around the world. A boiler’s function is to generate steam which is commonly classified into three different pressures (Low Pressure-LP, Intermediate Pressure-IP, and High Pressure-HP).
Boiler systems are comprised of numerous tubes, sometimes exceeding several thousand. Water chemistry is critical to mitigate damage on the interior surface of the tubes. Internal corrosion, erosion, open cracking, and pitting in tubes and pipes are common problems in both power generation and process plants. Oxygen attachment and hydrogen embitterment often result in complex internal flaw configurations that are difficult to quantitatively assess using conventional NDT methods.
By scanning the internal surface using a high-speed rotating laser profilometer, high resolution maps of the internal surface of a tube can be generated. By selecting the proper combination of sensor rotational rates and axial draw rates, pits as small as 0.025” (0.6mm) in diameter and 0.002” (0.05mm) in depth can be reliably and accurately mapped. Quest TruTec’s LOTIS® technology is uniquely positioned to facilitate this need.
