...-pressure, ILI, gas distribution Abstract A large majority of urban gas distribution pipelines are designed to accommodate future integrity management surveys with in-line inspection (ILI) tools. However, even with typical inspection design parameters considered, many pipelines end up on a difficult...

... of the six lines, 12 to 36 , have been inspected using the axial strain tool. The pipelines inspected cover a range of characteristics including, different vintages, pipe diameters and positions in the ROW. These differences, and the ILI runs provide an insight into the effect of a landslide event...

... methodology was applied to use data from multiple inline inspection (ILI) runs and field measurements with non-destructive examination (NDE) tools to increase confidence in crack size estimates. Multiple crack depth measurements were used in two different ways namely, to improve the characterization of ILI...
