Pipers data is highly repeatable, which means that changes in pipeline condition can be accurately determined over time. By establishing a baseline through an initial run, clients have the ability to use each subsequent run to gain a clear, comparative picture of the state of their pipeline assets. Affordability, ease of use, and repeatability of data make Pipers an optimal inline inspection tool for pipeline integrity program management.
Length of survey: 14 km
Pipeline diameter: 16-inch
Composition of the pipe: steel with expanded HDPE liner
Resource carried: fresh water
Client: Canadian energy company
Over a period of 17 months, INGU performed three inspections of a steel pipeline carrying fresh water. A deposit survey and condition assessment were carried out to establish a baseline reading. Data captured through two subsequent inspections allowed for condition comparison assessments. The inspection data clearly showed no significant changes in the magnetic flux measurements, enabling the conclusion that no major change in the condition of the pipeline had occurred since the first inspection 17 months earlier.
