Excavations to inspect buried piping are often costly and risk damaging other plant assets during the digging. Some utilities have used permanently installed guided wave sensors to monitor piping condition and reduce the excavations. The project that…
This project describes the long term overall development process with contributions of almost all major suppliers in the field. In the field application to buried sections of pipeline, especially those that are bitumen coated, the results are not…
Because of interest in using EMAT sensors in the PIG for circumferential guided wave defect detection and quantification analysis, this work was undertaken to explore computational modeling aspects for improved sensor design, and data acquisition and…
This document describes the analysis of performances of five non-destructive testing technologies for pipelines by propagation of ultrasound waves guided within the thickness along the axial direction. The tested tools are tools available on the…
Long-range guided wave pipeline inspection is claimed to be able to inspect ranges of well over 30 meters (100 Feet) in either direction (i.e. total inspection >60 Meters or 200 Ft.) from a single position. In terms of inspected meters per…
This project was intended to implement a guided wave flaw sizing technique and to ascertain its applicability to a range of pipe and flaw sizes. The report summarizes the modeling and analysis of laser mapped real corrosion data and presents the…
