Highly accurate measurement of the depth profile of corroded areas on pipeline or pressure vessels with the aim of performing FFS analysis.

LPIT is an inspection system that is tailored to follow-up investigation after ILI runs on pipelines. It consists of an automated system that scans the full pipe circumference, taking over 600 readings per square inch. An exact replication of the pipe surface can be produced in this way. The system enables reporting in the field, and initial analysis according to RSTRENG. The results of these measurements can be analyzed according to FFS codes like API 579, BS 7910 and ASME B31G.

Corroded areas on pressure equipment need to be repaired or assessed before further service can be considered. Current methods usually involve using tools like bridging bars, pit gauges and ultrasonic probes on a coarse manual grid. These methods are time consuming and sensitive to human error. In pipelines, where in-line inspection (ILI) runs may find hundreds of corroded areas, these methods may lead to lengthy and expensive projects that yield results inspiring less than the required level of confidence.
Applus RTD has been a pioneer in applying laser profilometry in the field and has several different inspection systems in use that are tailored to specific inspection situations.
